Not the OP but as a fellow non-American who likes to dabble in American politics I try to always mention that detail when I’m commenting on a hot/intense socio-political subject (like this one), so that the other people involved in the same conversation (presumably most of them Americans, both here and on Reddit) can judge for themselves how valid my opinion can be seeing that (most likely) I’m not directly involved or affected by the subject being discussed.

In my experience, people mentioning that they're not American (and in particular they they are European) seem to think that confers some infallible wisdom to their arguments

I just think you don't like foreigners

better than foreign propaganda flying under a false flag.
