I have met a couple of them in real life, and a few I have met online. The sample is not significant enough to draw any conclusions about their point of view and background.
I am more than interested in your opinions about the personality and political makeup of people who express this type of pro-C bigotry.
It’s no different from anyone else with arbitrary, narrow-minded views. People like that, whether they realize it or not, don’t believe in the intrinsic value of personhood.
This extends to their view of themselves and creates a need to feel valuable for some other reason. So they create a narrow idea of what it means to be good and valuable and it just so happens to align with their own traits, interests, and beliefs.
