I agree it's something worth considering....

We don't want McCarthyism, but can still be concerned about Communist infiltration into our institutions. So one can consider the motivation of the whistleblower, and the severity of the matter being investigated.

It's similar to an argument many of us have had with Trumpsters, including within my own family. Yes, I have no doubt some of the investigatory vigor directed at Donald Trump is politically motivated. That should be addressed and called out. But that doesn't mean it's OK for him to do the things he does.
