Right. Use these kind of hypocritical acts as ammunition with conservative supporters. They'll fight you. They'll get angry and defensive. They'll say it's not the same.
Don't let them get away with it. It is the same. Just keep saying that. Call them delusional. Call them out of touch.
Embarras the fuck out of them. They might not change their minds, but they will shut the fuck up and maybe even have second thoughts when voting.
Looking at the instance, it's horrifying, like 90% about fucking kids. They're not even trying to hide it, so regardless of other legal paraphilia, it IS a pedo community... so you'll be put on the watch lists too by joining.
