You can say McCarthy cried wolf, but that is 20/20 hindsight. YOu obviously aren't aware of the horrendous damage that he did to america. To the blatant abuses of the constitution he and Cohn perpetrated on innocent americans. It all started with a general fear of commies and he picked it up and ran with it a delusional attempt to "cleanse" america of its enemies. He got as far as he did, because only a few people had the balls to stand up to him, the most prominent being Murrow.
IN today's environment with the 24/7 news cycle, it would be impossible
He is actually advocating for suspension of the constitution, if he ever gets over his paranoia to consider it actually means.
This is nonsense plain and simple.
The notion that Islamist could gain any kind of foothold in the US is ludicrous.
