I got into it with a life-long friend (teacher) about obamacare, and our relationship hasn't been the same since.
For many folks, liberal thinking is not so much an ideology as it is a symptom of a personality development/maturity dysfunction. Same for gays and lesbians.
That's why we get all this insanity about rainbows and skittles and solar power and windmills with libs...they are at a level of maturity that can't get beyond "make-believe."
