This isn't surprising at all. Chechen people do come from Russia but we have a lot of conflict with people from Chechnya. Believe me, I hate Chechen people, the one time I ever ventured far south of Russia and ended up Dagestan (don't know why we did), I am surprised the group of friends I was with, did not end up shot or stabbed with how shit everything went quickly and it's not even Chechnya per se but I believe in the late 80's early 90's the Chechen Mafia was all over the place. Then one day they decided to invade Dagestan, Putin bombed the shit out of them and now Dagestan is some shithole that is completely ghetto.
Anyways I strayed way off topic. I've said this before when replying to a topic about gay rights some months back but gays aren't a big thing in Russia. This stuff happens all the time but not directly carried out by authorities, in fact regular citizens will even assault, kill or try to kidnap known gays. I mentioned in that post having a gay pride parade in Russia is like signing a death wish, especially if someone recognizes you. As mentioned above, Chechnya is unfortunately considered Russian since they are completely surrounded by us on all 4 sides, but I would say they're more of off the hinge when it comes to things. A lot of Chechen people are very shady and apparently others in Europe fear them based off the crime rate in Chechnya and the stories about a lot of them (despite there being I believe like 4 million of them.) Best example would be the Moscow Theater Hostage Crisis in which armed Chechen caused a terrorism incident and maybe the whole Russian soldiers being beheaded by Chechen's in the early 2000's and shared around the internet. There are other incidents about cab drivers in Chechnya kidnapping people and demanding money that could make people uneasy however that happens around the world, but still that and other stories like that do make some people uneasy about them. Turkey also sees Chechnya positively which does make some people also uneasy due to Turkey's own record. Islam also plays a huge role in most Chechen life, which further makes the fact that gays are being executed not surprising. At this point, this news should not surprise anyone because it's going to get worse, I would even say it could get to the point that it spews outside of Chechnya and along the borders of other Federal Subjects when it comes to authorities taking action; kind of like authorities actively crossing the borders going on witch hunts for gays. It can be said that Kadyrov is a Putin vassal as he would fight with Russia if a full scale war ever broke out between Russia and Ukraine, but Kadyrov is still seen as a gangster at the end of the day and the people he appoints are just as bad as him if not worse, I remember reading roughly 17 months back that his Defense Minister laid some sort of siege on a teenage girl's home until she agreed to become one of his newest wives.
