There are some people who take advantage of societal struggles and tensions for purely selfish ends.
However, misogyny is a real thing, and the struggle against it is a legitimate one. Women are consistently devalued in societies across the planet purely on the basis of their gender (sex), without regard to any other factor. To combat this, individuals and groups have to negotiate with the oppressing group. If negotiation is refused (and so often it is the case, as a summary judgment is declared that "women should stay in the home - period" or "women are mentally weaker"), then protest and civil disobedience comes out of that. The purpose of civil disobedience is to create tension. Why? Because by creating tension, you push an issue into someone's face so that they cannot simply ignore it. This speeds the resolution of the issue, because so often, without tension, the group with more power won't be particularly motivated to do anything about it.
Sometimes, this process doesn't work as planned. Sometimes, those who are in the oppressed group start to behave erratically and violently. Sometimes this violence is justified, however, there is a certain element of "getting caught up in the fray" that does occur in general.
When this happens, sometimes people in the group start to campaign for certain rights, without realizing the responsibilities that come with them. This is a learning process you can observe everywhere, with any child, and it applies to adults as well. Other times, people get so caught campaigning for something that they don't fully process what every aspect of the campaign means. And as I started with, sometimes people capitalize on the struggle for profit via guilt and manipulation.
Sometimes, we only see one aspect of a group campaigns. Perhaps this is what happened to you, @LevelZeroHero
Could you give a specific example of what you saw? Feminism is a very broad topic with a variety of beliefs within it.
