I think the approach he should have used is just not talking about it. I've never seen a leprechaun so I don't talk about them. No one thinks that's weird.
If I didn't believe in the existence of the clitoris (I do) I wouldn't say shit to anyone. Ever. That guy that tortured James Bond's grundle couldn't have beaten that statement out of me. Then I wouldn't have to declare anything satire.
I was on board with it being satire but I just browsed his tweets and I'm doubting that now. He talks about immigrants taking over Europe and retweets some questionable accounts.
But then there's some tweets/retweets that are pretty funny. It's the internet and I just don't know anymore.
He's probably doing the same kind of shit that "Alpha Male" boy does. I forget his name but it's pretty obvious now that it is "Satire". It doesn't make it any better though.
I had a buddy that used to satirize being an incel. He'd tell wild and obviously made up stories about his experiences and come up with crazy conjecture about why women didn't like him.
Unfortunately the incel community agreed with him and went even farther, so he had to stop for his own mental health. It's too hard to keep up with these groups.
