I've actually seen people praised for burning pride flags on private property. I've seen them praised for being a butthole to lgbt community. I do agree, the pride community shouldn't be praised for just attacking religious communities.
And the reason they get so mad about being told they're going to hell is because those people are being rude, now if it were said as a joke they wouldn't care, but it all depends on how jerky their being.
Also, ignoring bullies doesn't make the bullies stop, not always, I've tried that with my own bullies who have made fun of me for being autistic, and it doesn't work all the time, sometimes it just makes them bully you more.
