If they don't care about you as a person, they aren't going to care about your opinions, or your well-being either. You're just going to have to stop looking for reciprocal, caring support and normal respect from those who aren't capable of giving it. You don't expect your dog to rub your back when you've been working all day, even though you feed him, care for him, and rub him every day; or your... goldfish to make you soup when you're sick, even though you clean his tank and feed him. Some are capable of reciprocal care and respect, and some just aren't. Some are not even capable of seeing anything at all that you do, or hearing what you say, or remembering anything you've done, said, or been through. They just aren't, no more than a parakeet is capable of helping you figure out how to build a plane. All you can do is accept it, and learn from observation, and look elsewhere for real support and friendship
Using political labels to say who is "right" and who is "wrong", who is "GOOD" and who is "BAD"... does not create unity, but only creates separation. All of the political ideals have merit in some ways, and cause detriment in other ways, but humans have a hard time with this; they want one thing to be ALL BAD and the thing they like to be ALL GOOD. Ideas are not people, ideas are not alive, ideas do not create things. People who do things like identify themselves with an idea, and vilify anyone who does not go along with the "side" they have chosen voluntarily create separation. Just doing what primates do, identifying with a group, and calling the other group "THEM", instead of leaving ideas where they belong, in objectivity-land, where they can be viewed without bias and learned from, without becoming a cult.
