It's not about persuasion. The guy doesn't like feminism. What's there to persuade? He's not suddenly going to think "Oh, thanks for typing up a dissertation on why work still needs to be done for women to have to equal opportunity and choice in our community! I hadn't thought of it before."
He's free to not like feminism. I don't care. But as ck2 did, I highlighted how absurd it is that someone came in here with the implicit comment that if the project just made a simple change he wouldn't have a problem with it. That's absurd. If you have a problem with the word feminist you have a problem with feminism, which the project is promoting.
And doubly absurd that your issue is with me and not a community that flagkilled the story within an hour and upvoted a comment asking that the dirty f-word not be used.
