It’s because of Hank’s character. Take “The Alamo” episode. That is very much a Texas thing and he will die on that hill even if it’s wrong, but it also doesn’t really harm people to the extent that hating gay people harms people.

When it comes to the issues that causes society to turn on each other Hank often takes the approach of “you need to leave people alone and let them live even if you don’t like it” tactic, because that is what he wants for himself.
