If someone goes over what Reagan endured in Hollywood, when he stayed up all night with a gun to protect his family, then that person will see how dangerous the Reds were and are.

Huh?? what happened? .. I never heard this story before

[Chemnitz]

The Communists were intimidating Hollywood via a union. The actors were so frightened that they went to work through a drainage sewer rather than pass through the angry crowd of Marxists. Reagan, as union president and patriot, insisted on going through the front gate, sitting up and not hiding.
His life was threatened. He stayed up at night with a gun to guard his family, because of the threats. He really stood alone against the radicals. That is why he did so much to end the rule of the Evil Empire.

I hope I have the details right. Others should add or correct where they can.
