Darling if it wasn’t for the LGBT community, Eurovision would cease to exist in today’s ever changing world of TV entertainment. It’s a big gay festival after all, you only have to take a look at the Eurovision Village to recognise that. Naturally though, it can be enjoyed by those from all walks of life… but not those who seek to persecute a minority group simply for wanting to live their true lives.
It's big within the community sure and meant alot to it and vice versa, but it's still not an "LGB+T Festival" and even as a gay person myself I am not jumping onboard on that.
Anyways, strictly in terms of legislation (at least what I could find out on a quick research), Kazakhstan is actually less restrictive when it comes to gay rights than Armenia and Azerbaijan, and quite en par with Georgia, Moldova, Ukraine, Poland and Italy (to name a few, where the latter two basically have some cosmetical laws only due to EU membership), so if that's your criteria, I guess we should start to kick out countries then? But then again it is NOT an "LGB+T Festival" and whether one likes it or not, gay rights in countries have not been a criteria for entering Eurovision hence why ruZZia and belaruZ took part until recently and EBU still being keen on Turkey coming back (all three being more legislative restrictive than Kazakhstan) (plus the countries I already mentioned).
