That's all right OP, probably we all there in the past at least once.
Don't waste more time thinking about it, it is as useless as the debate was, so don't make the mistake twice.
Make this into a learning opportunity, and try to be more easygoing in the future. If you read something you disagree with to a level that it causes you emotional distress (you get excited, angry, riled up) then remind yourself to be more chill about it. Perhaps ask: should I really continue? You won't lose anything by not replying more.
I think it's fine having debates on the internet, have to learn to step back. Sure as he
>>351420 expressed they are mostly pointless, in the same vein we could say the same about basically anything - Russians tend to draw such conclusions.
Two cases from the top of my head when internet debates aren't pointless.
1. You have a thought and you want to test it by others. Perhaps they have different angles to view it, and ofc differing knowledge.
2. You want to learn something about someone else's viewpoint.
Perhaps there are other cases.
