If I misread the posters intent, then I apologize. That said, it is still a poor analogy.
I don't think you misread anything. You read it thinking somehow the poster was legitimizing telling a Jewish player that he was gonna get gassed. No honest reading of that post could have come to that conclusion. Only someone looking to take offense in everything could have read it that way. And in your incredible wokeness, you had to express your extreme outrage. Actually, you pretty much made his point...there seemingly is nothing that one can say that another won't twist and be highly offended.
