The principle of equal liberty is closer to anarchist political ethics in that it transcends both the liberal and socialist traditions
This entails that liberty and equality cannot be implemented within the state, resulting in the questioning of all forms of domination and hierarchy
A broad categorisation can be made between aims to destroy oppressive states and institutions by revolutionary means on one hand and aims to change society through evolutionary means on the other
Evolutionary tactics embrace nonviolence, reject violence and take a gradual approach to anarchist aims, although there is significant overlap between the two
Anarchist tactics have shifted during the course of the last century
Anarchists during the early 20th century focused more on strikes and militancy while contemporary anarchists use a broader array of approaches
Classical era 

During the classical era, anarchists had a militant tendency
Not only did they confront state armed forces, as in Spain and Ukraine, but some of them also employed terrorism as propaganda of the deed
Assassination attempts were carried out against heads of state, some of which were successful
Anarchists also took part in revolutions
Many anarchists, especially the Galleanists, believed that these attempts would be the impetus for a revolution against capitalism and the state
Many of these attacks were done by individual assailants and the majority took place in the late 1870s, the early 1880s and the 1890s, with some still occurring in the early 1900s
Their decrease in prevalence was the result of further judicial power and targeting and cataloging by state institutions
Anarchist perspectives towards violence have always been controversial
Anarcho-pacifists advocate for non-violence means to achieve their stateless, nonviolent ends
Other anarchist groups advocate direct action, a tactic which can include acts of sabotage or terrorism
This attitude was quite prominent a century ago when seeing the state as a tyrant and some anarchists believing that they had every right to oppose its oppression by any means possible
Emma Goldman and Errico Malatesta, who were proponents of limited use of violence, stated that violence is merely a reaction to state violence as a necessary evil
Anarchists took an active role in strike actions, although they tended to be antipathetic to formal syndicalism, seeing it as reformist
They saw it as a part of the movement which sought to overthrow the state and capitalism
Anarchists also reinforced their propaganda within the arts, some of whom practiced naturism and nudism
Those anarchists also built communities which were based on friendship and were involved in the news media
Members of The Invisible Committee were arrested in 2008 on various charges, terrorism included
Overall, contemporary anarchists are much less violent and militant than their ideological ancestors
They mostly engage in confronting the police during demonstrations and riots, especially in countries such as Canada, Greece, and Mexico
Evolutionary 
Anarchists commonly employ direct action
Decision-making is often handled in an anti-authoritarian way, with everyone having equal say in each decision, an approach known as horizontalism
Those anarchists would rather base their thought and praxis on their own experience which they will later theorize
The decision-making process of small anarchist affinity groups plays a significant tactical role
Anarchists have employed various methods in order to build a rough consensus among members of their group without the need of a leader or a leading group
One way is for an individual from the group to play the role of facilitator to help achieve a consensus without taking part in the discussion themselves or promoting a specific point
Minorities usually accept rough consensus, except when they feel the proposal contradicts anarchist ethics, goals and values
Anarchists usually form small groups (5–20 individuals) to enhance autonomy and friendships among their members
These kinds of groups more often than not interconnect with each other, forming larger networks
Anarchists still support and participate in strikes, especially wildcat strikes as these are leaderless strikes not organised centrally by a syndicate
As in the past, newspapers and journals are used, and anarchists have gone online in the World Wide Web to spread their message
Anarchists have found it easier to create websites because of distributional and other difficulties, hosting electronic libraries and other portals
Anarchists were also involved in developing various software that are available for free
The way these hacktivists work to develop and distribute resembles the anarchist ideals, especially when it comes to preserving users' privacy from state surveillance
Anarchists organize themselves to squat and reclaim public spaces
As seen by anarchists, squatting is a way to regain urban space from the capitalist market, serving pragmatical needs and also being an exemplary direct action
Acquiring space enables anarchists to experiment with their ideas and build social bonds
Key issues 

As anarchism is a philosophy that embodies many diverse attitudes, tendencies, and schools of thought; disagreement over questions of values, ideology, and tactics is common
Its diversity has led to widely different uses of identical terms among different anarchist traditions which has created a number of definitional concerns in anarchist theory
Anarchists may be motivated by humanism, divine authority, enlightened self-interest, veganism, or any number of alternative ethical doctrines
Phenomena such as civilisation, technology (e.g
within anarcho-primitivism), and the democratic process may be sharply criticised within some anarchist tendencies and simultaneously lauded in others
The state 

Objection to the state and its institutions is a sine qua non of anarchism
Anarchists consider the state as a tool of domination and believe it to be illegitimate regardless of its political tendencies
Instead of people being able to control the aspects of their life, major decisions are taken by a small elite
