Serious question: how many MRAs change their minds on the issues and reject mens rights wholesale to become feminists?

I see a lot of feminists tend to hop on and embrace mens rights, going as far as to shed the feminst label. Cassie Jaye, Erin Pizzey and Warren Farrell all come to mind. Have there been any notable cases of the reverse? And if it has, what was the fallout of that? Was it just pure drama or did the movement just shrug it off?

Mostly just curious. I think it speaks a lot about the nature of the mens rights movement that more people seem to be crossing the aisle in this direction, but I don't want to judge on limited evidence.
