This may not be received well, but I’ll try anyway. Yeah debate can definitely be polarizing, but I appreciate people that bring a reasoned argument to the table without being conflicting. When that happens I have a little more faith in humanity even when their opinions are different than my own. It’s a give and take and it sounds like in your situation you felt like you were the only one trying to have a civil discussion. That is exhausting.

Honestly if I talk/debate with someone long enough I can tell if they won’t be convinced, but sometimes it’s not the person you are debating that you are going to convince, but someone on the sidelines. Honestly the people that are most vocal are likely the ones that are already polarized and irrational, but that doesn’t mean the world is full of irrational people. Sometimes I believe not participating in an online debate is the right thing to do, but on the other hand the only way the tone will change about politics is if people change it.
