Because that sounds like the *worst* place to be. Ever.
This is almost funny and almost genuinely terrible. A group of 4channers have decided that the best way to mess with feminists is to create a fake convention. The convention would take place at a gay bar. Because apparently that's like... the worst place they could ever imagine going.
There was a scam going on underneath this incredibly ridiculous prank. An account on Sellify was created to sell $50 tickets to the event. It has since been taken down. It took less than 24 hours for the entire thing to be torn apart on twitter. Sorry not sorry 4chan.
