When did America start to hate communism so much and why? Of all the countries in the world America is surely the last one that would ever go over to communism, I imagine you could count active communists in the Sates in hundreds not even thousands.It's seems especially during the McCarthy years that the reds under the beds scare was just that, a scare. I know the then Soviet bloc had 'the bomb' but they were hardly going to invade in all honestly, they simply couldn't have afforded to. Nato matched them for weapons so it was always going to be a stand off. So honestly, why are Americans so afraid of communists? Other countries have them and they've never actually bothered anyone, being, frankly political no hopers, even the Labour Party here doesn't rate them.
