"as if every Democrat had to state for the record they are not a member of the Communist party."
Or every Muslim to state for the record that they are appalled by terrorism?
There is a not-so-small subset of conservatives who view all Muslims as terrorists and demand statements of condemnation of terrorism from every Muslim they can find, with the implications that the Muslim is probably "one of them".
Regarding conservatives, what I see more of of is people demanding that conservatives who state in private that Trump's stream-of-consciousness ramble after Charlottesville or other comments of his or his insane tweets are appalling be willing to state so in public.
We have Republican leaders who leak to the press they are appalled. Republican leader X telling a reporter that, privately, s/he is alarmed by Trump blurting out comments on important issues.
Step out of the shadows. Speak up.
