While gay sex was never illegal there there’s a couple of “public indecency” type laws which allow police to harass folks. Regarding public sentiment: If tomorrow you had a referendum whether civil unions should be introduced it would not be unlikely to pass, pro-marriage and pro-union are almost 50% with 30% undecided. And don’t think that protesters for other stuff are treated more kindly.
Comparing the situation in Turkey to that in other Muslim countries, as done in the icky portions of the post replies, (except say Albania), is dishonest and misleading as fuck: Most problems arise not really because Turkey is a homophobic shithole, much less a particularly homophobic one, but because it’s a shithole. Go ahead, try to outlaw alcohol in Turkey and you’ll see how much arguing with the Quran is accepted there.
Bonus song (enable subtitles). Oh and someone has to explain to Turkish machos that bullying bottoms is totally gay.
