Someone refers to me as a "loser", or suggests that I am a "pay piggy" and I either verbally eviscerate them publicly (and I mean I'll really go for jugular) or... having completely lost any ounce of respect I had for them, they really won't hear anything from me, ever.

I've had a great time on prodomme twitter, personally. Not much disrespect and anyone who tries it gets swiftly blocked and forgotten.

It sounds like you're following a bunch of bratty online findoms and that's just not your fetish? They talk that way because it appeals to their customers. They're mostly online-only so they don't have the same need to separate fantasy from reality. If you're not into it, it's not directed at you.
