If you want to make an impact maybe posting a bunch of those 1 foot x 2 foot concert style posters around the convention center would accomplish something.
If you just want to experience it then I say go for it but I don’t think protesters have much impact. Dubs are trained to look away fast.
I saw a post a while ago about a Mormon throwing the JW’s protest about the Mormon leadership back in their face since theirs isn’t much different.
Maybe you could pretend to be Mormon or some other religion and hold up signs highlighting things those religions do that the dubs would complain about but that they actually do too.
Maybe they wouldn’t be so averse to stuff it it wasn’t specifically “apostate”.
