Russian Eurovision representative, Polina Gagarina, is there to sing a song to the continent and not to promote any agenda against the LGBT community, Ukraine, or any other political issue. As such, you should not boo her (or any other act) under any circumstances, not even if they receive 12 points during the voting, or give their own 12 to a nearby country. Booing Russia is not some defiant act, nor some funny joke amongst those in attendance, it is simply very rude towards the artist, and not in line in the unifying messages that Eurovision aims to spread, and if you do boo her, you are an asshole. Just don’t do it.
