The most surefire way to piss off a Trump supporter is just to be a decent human being in their vicinity. Or on the internet. Or in movies, TV, or video games. Or in complete private.

Nothing.

They’re already brain dead.

Always have been.

Fauci did nothing wrong.

the truth

They're already pissed off. That's why they support Trump.

That being said. Here's some options:

ACAB

Actually Obama looked good in that tan suit

Single payer healthcare is a good idea

I think I'm a socialist

Say you love how Trump is the most American president ever: by being a mostrous, braindead, clownish genocidal war criminal, the living perversion of a caricature, narcissistically self-serving, yet 100% the goon of the billionaire class, he perfectly exemplifies US culture, history and politics across parties. No one else ever truly represented both Democrats and Republicans better. Democracy in action.

Just loudly wonder when he's gonna release the Epstein files. It's been so long and you're starting to get suspicious

You could also ask them about how it feels to be unable to satiate their bloodlust for brown children by losing the Iran war, and then get economically fucked for it as well. Just nothing but L's on all fronts from their perspective

to piss them off?

Open your mouth

Walk up to them and say "I am the woke left, I am the one who spread the leftist agenda"
