That is the internet for you. You say one thing in disagreement with one party, they automatically think you're part of the opposing party. It's so damn stupid. If anything, I can't stand most politicians as they're for the most part, corrupt and don't care about anyone but themselves.
I've commented on politics in front of my family in the past, and I'd say my family is mixed when it comes to who they prefer. Some of my family is for Trump, some for Biden, and some just don't care. I'm in the latter in that I don't care about half the people running for president, because none of them are for me or us in general.
And the same goes for social media. It's pointless to say anything these days, because people will try to make you the bad guy, or will try to paint you as someone who believes in something you don't. I can't be bothered about Biden or Trump anymore. Because soon enough, we're going to see these two at it again in like 2024 I think. I think I'm just going to ignore most news outlets around that time. I just don't care anymore.
