I dunno about that... I've experienced more interaction with Trump supporters than the opposite... which is not to say that I haven't been able to have good conversations with Democrats. However, a fair majority of left-leaning conversations usually end when I present a fact/figure/static/etc. to push back on a topic and they insult me or leave. There have even been times where I was shut down immediately and called a race traitor... which is odd... because Democrats are supposed to be all about being tolerant and such.
Right-leaning and those people who are politically center seem to be able to have the most fruit debates. But that's just my experience and is, thus, anecdotal. Not sure if that changed your mind but maybe it's something to consider.
