Having moved from the liberal coasts to Texas, I can tell you that you're right about the opposite experience happening too, and you definitely don't have to go looking for it.
I found it amusing that a man who was going to take an oath to defend the Constitution thought it was reasonable to call me un-American and try to beat me into silence. He left when I laughed at him instead of fighting back.
I had friends un-friend me on Facebook after my sister married a woman and I posted pictures and congratulations to them. I had colleagues who stopped talking to me after the same. They talk to me now (2 years later), but only professionally, formally. No more informal or loose friendship happening between us apparently.
This shit definitely happens on both sides.
If Trump hadn't done that, I would have gone for eternity judging those people as war mongers no matter the cost.
If Trump hadn't said "I want some punishment for the woman" on abortion, I would have gone for eternity judging all anti-choice folks to be for incarceration of women for exercising choice.
