I have grown a serious hatred towards 40k and have never once played it.
You should at least give it a go before you decide you hate it. 40K has a lot of problems but it's still fun despite them.
Too bad it is so disgustingly expensive that "just giving it a try" is not practical. That game is going to have to radicaly change or die sooner or later, because the alternatives have so much going for them.
And a lot of folks despise it for the cultural attitudes that it breeds, far more than any actual gameplay considerations of the game itself. It seems to breed a certain kind of toxicity, and that can spill over to elsewhere.
That at least is not true around here. A lot of the 40k guys are really cool and it is a lot of fun to talk about painting and general hobby stuff with them. They are happy to share their bi-weekly meeting with players of other systems and the atmosphere there in general is fantastic.
