With the same kind of reasoning you could say “The guy was beaten to death for being 65 years old, because if he was 2 years old, he wouldn’t have been room mates with that guy, and then he wouldn’t have asked for a cigarette, and then there wouldn’t have been a fight over that, and then he wouldn’t have been beaten to death”.
If you say “He was beaten to death for smoking”, then smoking would have to be the main (if not only) reason for that guy to have been beaten to death. Which was clearly not the case.
Ok, here’s something resembling an actual source: lawandcrime.com/crime/kicked-his-a-pretty-good-man-clobbers-drunk-roommate-asking-him-for-cigarettes-to-death-with-box-fan-and-stomps-to-his-face-cops-say/
The guy didn’t kill the other one because one was a smoker and the other one wasn’t.
Instead, both were smokers and one asked the other for cigarettes, which is what caused a fight and caused one to kill the other.
Thus: nobody here was killed “for smoking”, as the comment you replied to put it.
So how does that relate to violence between gay and non-gay people?
And you’re saying if the smoker wasn’t a smoker they wouldn’t have asked for cigarettes so they wouldn’t have been killed.
That’s such a weak chain of reasoning.
