"If I can guess your stance on 10 specific, disconnected issues, from just knowing your stance on 1, you're most likely an idiot and not worth talking to". 😂
I've observed this often myself in various political parties, religious groups, etc. Not only are the issues disconnected, they are often even logically inconsistent. But the vast majority of people fall into this category to some extent because "group think" seems to be part of human nature, so you probably still should talk to them.
