Jacobin did an article about their analysis of his entire decades long Reddit posts - they read every one. And he does express his Anti Trump and anti Trumpian admin and anti fascist and anti authoritarian stuff. Link to my post is here if you would like https://www.democraticunderground.com/100221290750]
A few examples
Progressive, but Not Woke
Gun control aside, most of the political positions Platner expressed on Reddit were conventionally progressive ones: pro-vaccine, pro-LGBTQ, pro-universal health care, belief in climate change, virulently anti-Trump, and enraged by January 6, to name a few.
Platner typically expressed them in the same vulgar, politically incorrect way that has dominated recent headlines. Trump was a f*cking c*nt and a mentally incapable narcissist, the latter next to the word retarded struck through. Oliver North was a lying piece of sh*t. A Capitol rioter asking for clemency was a f*cking worthless pussy. And a traitor. A former congressman who cheated constantly on his wife was the epitome of the frat bro officer douchebag.
And
Customs and Border Protection asking people for their papers at a bus station was godd*mn disgusting. A Republican state representative voting against providing prisoners with menstrual products was a f*cking asshole. The group of marines investigated for allegedly sharing nude photos of their female coworkers, Platner wrote, were f*ckwads and just losers who hid behind a computer and camaraderie to justify their hatred of women, adding, nail these f*cks to the wall.
