You need to educate yourself; you're damned dead wrong about McCarthy! He was a HERO of monumental proportions and no nut.

My friend, I say again, I lived through it: I was there. He started off with good intentions but, as with many politicians he started feeling invincible and smearing people without adequate evidence [much like the syncophants of our former Pres., Bill Clinton].
You will find most people have both good and bad qualities and it is never a good idea to accept someone's view totally.
