That's pretty fair. My experience (while young) was similar. I am mainly speaking to the racist side of things, that seems to apply to religions including, and outside of, Christianity. At some level, it's like politics. Some folks will vote Democrat because that's what they do, some will because they see that as their best option, and some will be activists within that system to foment change. But politics in USA is not religion if you are left leaning so it is harder with fewer real options. Probably no racists vote for Democrats.
