Well, you are still young yet DazedandConfused, you will need to take this slow and make up your own mind about your cousins. If you are uncomfortable around B then that's a cue that you do need to be cautious. Discussing politics is ALWAYS risky because someone can quickly develop a hate for you if you don't have the same opinion they do. So, you were right to distance from cousin B that began ranting on social media. The political climate has been absolutely attrocious these past couple of years anyway. Many people have chosen to just keep their opinions to themselves, a smart move. Also, you are getting to an age where if you want to send gifts to your cousins you can choose to do that on your own. After all, you are going to be your own person now and form your OWN opinions about things. It does sound like cousin A is nicer from what you have shared. You can always send a nice card and ease your way back into their graces if you wish to do so. You don't have to engage in conversations that make you feel uncomfortable, you can choose to step back and not entertain any rantings. Sounds like cousin A knows how to do that unlike cousin B.
