Who's asking government to fight an idea? However, the voters should know who espouses those ideas so they can vote them out of office.
People who were members of the Communist Party in the 1950 were agents of the Soviet Union who took orders directly from Stalin. As such, they were enemies of the United States and should rightly have been barred from employment in sensative government positions. Anyone who disputes that position is simply a Communist himself, a fellow travelor or an imbecile.
McCarthy was fighting an idea, that's why he lost.
USSR ended up with all our secrets, mostly by pay-offs and blackmail, didn't help them a bit.
More like American spies sold them secrets...
Over the years many natural born US citizens have been caught selling top secret information to the Russians....
And to the Israelis...our allies.
