I mostly agree with your response, except for chastising OP about the color of the shirt. They start by mentioning brown, then parenthetically say "orange" as an unveiled reference to Trump.
This is because Trump is known to use a LOT of bronzer that turns his skin an unusual orange color. So what OP was trying to do was to relate the brownshirts to the presumed task force that Trump would create if he became a dictator.
If you're not skeptical of single issue leftists, then you should be more skeptical in general.
We know that there was a LOT of foreign astroturfing in 2016. And 2020. 2024 will likely repeat this trend, but armed with AI.
We've already seen one weak "it was AI and fake" argument from Roger Stone. Going to see a lot more of that this year, too.
So he careful who you trust, because they just might have an agenda.
