I could only think of one practical use of this law: if you ban gay parades in Russia you would decrease raising numbers of broken jaws and ribs.
I mean what's the sacred point of gay parades anyway? I don't get it. I feel like these parades inhabited by exhibitionists rather than gays.
I also think that any public actions of sexual nature(including gay parades) are in fact sexual harassment to the society. And sexual harassment cannot be considered as acceptable, in my view.
I mean if you are a gay - fine. But don't stick your genitals to the faces of other people.
Go to Vegas, rent a place and stick it to the faces of people who give a damn. AEE does it, so should gay people do, if they so fond of their parades.
