If someone accused you of being pro-Trump and you said “I’m registered independent” do you think they’d be like ‘oh, nm carry on then’?
If they asked I would say ‘no’ instead of trying to dodge the question.
You asked about something specific, whether someone was ‘officially’ something and I answered the question. You asked a question that is apparently different than the thing you want to argue about, which is who they (currently?) support.
