Question for the anti-feminist, is it true that many anti-feminists were formerly pro-feminist?

I'm sure a lot of people once thought that feminism is about "equality". But to speak for myself, no, I'm not a former pro-feminist but I wasn't an anti-feminist either. Like pretty much everything else, my stance on feminism was neutral when I was first exposed to it. That is until I start to do some research, look deeper into it and learn of the true [misandric] nature of the movement - from that moment on I'm an anti-feminist full force.
