It goes beyond hashtags. I was speaking more to the structure of discourse. Even people who are used to speaking in public, on record, in front of cameras, frequently fail to engage with others properly on Twitter. That’s pretty intimidating to me. There just seems to be so much nervous energy on that platform. You could enjoy your day, write one tweet just to express your thoughts on something before going to sleep, then have people halfway across the world jump down your throat and wake up to a nasty surprise.

I would agree that Twitter's design has led to a lot of toxic discourse, but I would disagree that it's the result of people not knowing how to use the site "properly." Quite the opposite - that's what the intended usage of Twitter leads to.
