You, meanwhile, took it as an opportunity to bash the victim for his religious beliefs. Most reasonable people would therefore take you to be behaving as a hateful bigot. No matter what word games you try to play hereafter, you look like the stereotypical sneering anti-theist who has an axe to grind, rather than the level-headed rationalist you probably imagine yourself to be.
