Clicking off into some of the twitter links is a depressing read; the linked Susan Glasser tweet was horrendous. Endless people(?) (more likely Twitter bots I would think) parroting the "Yes, Tulsi is a Putin stooge", "Who's funding her campaign?", "She's a GOP plant" line and other incredibly stupid things). Leah McElrath is dreadful too.
The thing is if, even now, you can have so many people think that the U.S. hasn't been engaged in regime change wars in the Middle-East and that to suggest they have is a "Kremlin talking point" what chance does truth have and what chance is there for change? That's assuming the tweeters are people and not bots, which is a big assumption.
