Oh, do not blame yourself! Do you have gay parades? Honestly climbing each other into cowards in public places gay? Harassed a colleague of non-traditional orientation at work? Have you actually watched this at least once in your life? Have you ever heard of the "second hand"?
You’re angry with gay people just because they’re different from you. For some, this is enough to offer mass shootings. And take such a damaging monster to power - first gay, then Jews, then those who painted their hair in an unstable color, well, and so on. When they come for you, no one will stand for you.
