It's always the same with those right-wing populist guys. They post links as "proof" of something and when you take the time to read the linked text, it's usually just the opposite of what they are saying. And when you point that out to them, they say it's the (assumed) spirit that counts, and that there are other (unmentioned) points that proove their point.
In this case insisting on something being "public indecency" but failing to see that their view of public decency is neither a universal one nor should a tolerant society ban things only because they offend one's own side. I mean, does anybody really believe that a child will become gay/trans/hetero/... from exposure to someone being openly gay/trans/hetero...? What's so wild about people dancing around scantly clad, maybe waving some dildos?
I'm pretty straight, and I'm not the most secure person ever, but I'm not that insecure that this offends me in any way. Which sould be a view that should also be accepted.
I do live next to hungary, and I know even hungarian gays that support that asshole Orban because he tells them that he is against Islam and foreigners. In the end, this is just a war between tolerance and intolerance, democracy and fascism. To tolerate something, it has to be something you don't like. Except tolerating intolerance, obviously. It's not "freedom" to fabricate excuses like "we have to protect our children from public indecency" to force people to act in your worldview.
