This matches my experience also: both men and women can both get really unpleasant when you upset their carefully curated echo chambers.

It's better, in my experience, when you use carefully sourced objective information provided in links, but that alone is not enough.

It's also not just conservatives.

I don't know if this is true--it would be hilarious if it were--but my subjective impression is that after the "liberal snowflake" and "facts don't care about your feelings" memes from the right, conservatives have a reduced propensity to block people and an increased propensity to engage in dialog. But I never can really tell--all this stuff is sculpted so heavily by recommendation algorithms, so maybe I just get shown stuff now by conservatives who don't block people, whereas a few years ago it was by conservatives who do.

P.S. I also have the "discuss forever" phenotype. It's a really hard habit to break--if you have any tips that don't require one to compromise one's commitment to rationality and dialog as a way to resolving disagreements, I'd love to hear them.
