It's alright, I'm not shy to the flagging and downvotes. I appreciate your thoughtful response
From my understanding, your argument is a variation of "many/all things are politics and therefore politics cannot be disentangled from the topic" which I've seen others mention before. Sure, you can find ways to connect things to certain policies and politicians and then talk about that solely. Yes, economics becomes politics and recent tariffs are certainly policy-related. That doesn't mean we must discuss the political aspects of it.
The problem becomes that jumping to politics is very polarizing, identity-driven, and quickly drowns out curious discussion. The OP made a political statement, which won him easy points to push his comment to the top since there are so many who share the mindset of OP's comment. Any discussion about things not directly related to politics was pushed down. The effect happens across threads so frequently that no other conversation is left but politics. Those who don't want to talk politics spend time elsewhere, creating a feedback loop.
PG has a great essay about this here:
