He came out publicly because he was invited as guest of honour to a Russian film festival, the point was to draw attention to their atrocious laws. It was very thoughtful of him to out himself like that.
It's pathetic people would cynically attack him over this.
Agreed. This is a perfect time to come out if one wants to send a clear message to those who would be hateful and bigoted. Might as well use that notoriety for something positive.
