I’m telling you: use their own tactic against them. Start calling them “hoplophobes” ceaselessly. They LOVE the term “homophobe” because it implies something is wrong with the person who finds homosexuality distasteful. Make their argument an irrational fear.
Some will argue, “Well of course I’m afraid of them - they’re dangerous.” Respond mockingly: “I know! Spiders, too! Those things are venomous! They can kill!”
I think that’s a bit obscure. I just ask all gun grabbers:”Why do you think you should be able to curtail my civil rights?”
