Calling someone a racist/etc. is more of a personal opinion than an accusation. As an opinion it need not be proven! The generic form is ‘I don’t like you’.
Suggesting action because you don’t like someone requires backing to match the action.
And I drove through the Tri cities yesterday. But why should you being a real (if not pleasant) human being have anything to do with whether you’re a Russian troll? We have lots of Slavic immigrants around here so it’s a very real possibility.
Said no dog, ever!
