Just out of curiosity, roughly speaking where do you draw this line between protecting your culture and free speech?
What if the group in Moscow simply wanted to hold up signs saying "No homophobia" and "End discrimination against homosexuals"? No orgies, no dancing nude men, no lewd acts...just sending a message that gays deserve to be treated with basic respect in society.
Should a society be able to legitimately shut down this protest using government force?
There is no line between protecting the culture and free speech. The problem lies with the defining down of free speech. We're told that parading naked and publishing every kind of depravity is free speech, but some of us do not agree that smut is Constitutional free speech.
If homosexual activists want respect, then they should act respectably. That includes keeping their private business to themselves. This is such a simple concept that it boggles my mind that no one seems to understand it. Figuratively waving one's genitals in public and insisting that everyone accept it is not respectable, and it is obviously not winning any converts. Duh.
Our society does not shut down this sort of thing, and what other societies do, again, is not under our control.
