Look: nobody should ever lose his job for voicing political opinions in his capacity as a private human being --- and yes, this principle applies to political opinions you or I don't like. What's going on right now is no different from 1950s blacklisting except that the sides are flipped. If you object to McCarthyism and don't object to this, then you're just a partisan unmoored to any principle of discourse higher than getting your team to win at any cost. You can be that way if you want, but you should at least be honest with yourself about it.
