In todays society citizens are the main pushing force behind ideologies. For example if someone creates a new ideology, this does not mark the start of a change, but when the citizens band together into groups they begin to accept and follow the ideology, this is when change is made. From this we can see how important individual actions are to an ideologies everywhere. This topic can be argued as well, not every individuals life is based off ideologies that others push on them, but because some of these actions are done simply because they are part of the social or legal standard. A great example of this in our everyday lives is paying taxes.
When an individual has an ideology that is opposite from the one in power, they have to opportunity to express this because we have the right to a free vote, right to free speech, and peaceful protests. These are all ways that allow a citizens can act directly based of their individual ideology. In our modern society there has been numerous non-violent ways to act in the interest of opposing ideologies. For example the Anti-war protests on the war in Iraq. Some people have even made a career out of opposing to certain ideologies.
Every Citizens have the right to openly support and follow their own or chosen ideologies. However, as stated before when these actions cause a threat to others or the general society, they are not acceptable in our society.
