Just the fact that people like Hillary (so the grossest neolibs) were out screaming "Assadist!" at people for years was enough for me to go "Knowing nothing else about the situation, I can assume Assad is not the primary issue here." Similar to Putin or even Hezbollah and Hamas. Any or all of these organizations and/or people can be "bad" by some sort of moral standard. Think what you will.
The fact will always remain though, that the US doesn't oppose Hezbollah for their stance on gay people. They aren't against Putin because he has irredentist desires in his region. If the US was actually bombing countries for being anti-gay and irredentist we'd be bombing... ourselves, first off (extremely homophobic and transphobic country). And we'd be bombing Israel for being anti-gay AND constantly annexing territory illegally. So any claims by the Hillary-types (using her as an archetype) that "Assad is bad because X" "Hamas is bad because Y" "Gaddafi is bad because Z" ultimately is meaningless propaganda. Even if claims they make are true, the US and policy makers in the US are absolutely not the people who get to stand on some moral high ground. Anything Assad may have done, the US has done worse and to a greater magnitude.
I feel like I'm constantly going in circles repeating myself, but I guess all we can do is digitally scream at and humiliate liberals until they just shut the fuck up basically. If they wanna yell at someone, I can give them a healthy list of far worse people who have way way more power than Assad. Joe Biden is a start. Chuck Schumer. Fetterman. Even Bernie Sanders. Go yell at these people. Yell at Trump. Have fun. Just shut the fuck up about "ooohh Syrian bad man! You won't condemn him! But he is Putler and Hitler and son of Iran! Why not condemn? Why do you hate Taiwan???" (That feels like some crazy shit I'd actually read in comments on Twitter from libs)
