For me, it was being outraged after learning about AWDTSG and other "Tea Groups" recently, and then starting to read and engage in this subreddit and other men's rights and egalitarian subreddits. Also, I was firmly pro-feminist before then, but that caused me to start to question feminism.

I stopped identifying as a feminist and turned against feminism, after watching and reading about the collosal harm feminism has done to male victims of rape, sexual assault, domestic violence, and intimate partner abuse, and how feminism largely caused these issues to become falsely gendered, and for male victims to be erased and be given almost no protection and support, and for female perpetrators to be erased and be given near total impunity.

I learned about Sandra Horley, and how she helped erase and take away support and protection from male victims of domestic violence and intimate partner abuse, and helped keep female perpetrators unaccountable.

I learned about Mary P Koss, and her manipulation of statistics, and her denial, apologetics, and erasure of female-to-male rape.

Another thing that helped me fully "wake up" about feminism was a post I posted here talking about our relations with feminism, and reading your counter-arguments in the comments. I want to thank everyone who commented on my post. You also made such good arguments, and were so understanding.
