Kinda depends on what "liberal" means. If modern liberals were as they were in the 90's, I'd be one of them. That's not even all the way back to classic liberal, but close enough. Modern liberals, though, are not critical thinkers, and their efforts have destroyed too many lives.

If you’re referring to cancel culture then yeah sure, I think that has definitely been enabled by social media / addictive tech. Echo chamber + broad distribution = shitheads can really fuck some things up. One can be progressive without being a shithead about it.
But moreover I think it’d be prudent for the sake of civil discourse to separate one’s political views (progressive) from the way one conducts themselves (shithead) otherwise you just begin to believe all progressives are shitheads. And yes I can switch the term “progressive” for “MAGA” and the point still stands.
