Go listen to a Vanessa Beeley interview. She exposed the truth years ago. Meanwhile we had freepers posting here about barrel bombs and that anyone opposed to removing Assad was a Putin stooge. I suspect some were zotted. How many were here simply to promote deep state propaganda?
I don’t know the motivations of people who parrot Hillary and the Deep State. I suspect some of it is guilt for being on the wrong side during the Cold War (remember, it wasn’t Democrats who thought Reagan was an idiot, risking a war but re-arming the US) - so they want to come across as tough guys now, standing up to Russia, etc.
For others, simply ignorance...they’re too lazy to do their own research.
If you haven’t seen this yet, watch it - and keep in mind the reporter works for PBS, he didn’t set out to provide propaganda for Assad, not at all (lucky for the Deep State this video didn’t go viral):
