I've heard of it. That Nikolai Alexeev you speak of is one of the main activists of the gay movement in Russia. He is well known for leading several gay pride organizations and struggling for the legalization of all kinds of gay rights - propaganda, marriage and, unfortunately, much more.Has anyone heard of or seen this notice? Honest answers, please.
It should be noted that this guy is not just an ordinary deviant. He was taken by the police several times and even tried to sue Russian Federation in ECtHR. Almost every month he tries (and fails) to organize a gay parade in different cities across Russia thus making people quite angry. Even other gay organizations dislike him sometimes because his activities tend to cause more hate rather than admiration towards the sexual minorities. He is the type who struggles for the idea more than for people.
I would say even more - most of the modern "antigay" laws are actually the consequences of his actions too.
As for me, I don't like him. I wouldn't mind if this crazy man was removed from the society - it could make the life of both normal and deviant people much more peaceful.
