Do your part and engage these hateful people. Show them love. Tell them you're queer and support LGBTQ people. We won't squash hate by ignoring the problem.

You'd be surprised. Like habits, old thought patterns die hard, but nearly every person with a bigoted view that changes their mind does so after meeting people who don't fit the mold their prejudices try to force them into.
Your conversation might not change their mind, and they may never change, but if their narrow worldview does one day crumble it'll probably be a death by a thousand cuts so every little cut makes a difference. Even for the devout the cognitive dissonance is always there somewhere. Feel free to feed it when you get the chance.
