Ideology only exists in the minds of people. It is not possible to fight an ideology without fighting people. Doesn't have to be physical fighting, could be ostracization or civil disobedience, but if all you're willing to do is say you disagree and not back it up with any action then don't be surprised if the culture continues to devolve at an accelerating pace.

Taking a stand may turn people off, but a lot of those people are the people who aren't going to join your side for any reason. Standing up also helps encourage those who agree with you, who are either less aware or more timid, to take a stand as well.
