Something I’m gradually drilling into my head:

If someone’s worldview amounts to dividing up the world into Good Guys and Bad Guys, and if this person is friendly towards you & you want a good relationship with them, it’s prudent to always presume that it’s mutually understood that you’re one of the Good Guys. Even if you think their Good Guy/Bad Guy categorization is unfair; even if you think you logically would fall into the Bad Guy category, by their definition.

If they like you, they already believe you’re a Good Guy, and are not strictly abiding by their own “rules.” Stop being shocked that people can be unprincipled; it’s true, and it means that you can’t change their worldview by going “you like ME but I’m one of the Bad Guys, checkmate!” Accept the unprincipled favoritism, or decide you don’t want a close relationship with the person.
