I can believe in giving fair criticism of Biden, while believing also that the absolute tsunami of total bullshit criticism that comes in a very particular style of interaction that's markedly different from organic comments, is probably exactly what it seems like it is.
I don't think I ever accused any specific person of being specifically Russian, but yes I believe that most of the drumbeat of Biden-is-bad-for-this-made-up-reason-no-I-will-take-no-questions comments represent an organized shilling effort.
