We all know the rest of that question...
Senator McCarthy is remembered for that due to the exact same processes and types of people who are responsible for the current mess, the Left, inclusive of Democrat Party, Media, Entertainment, Entertainment, adding in Big Tech.
Those same people who slandered McCarthy and salted the earth over his very grave to eternity as a disreputable and evil person are the ones who are going to perform the exact same hatchet act on President Trump and Conservatives.
We should no more participate in the slander of Joseph McCarthy than we should in the current and coming slander of Trump and his supporters.
