I am a capitalist, and an American. Some things have been done to protect capitalism that I don't approve of. That doesn't mean I'm not to be counted as the enemy of communism, socialism, and any other system that seeks to destroy America and capitalism.
So, I stigmatize anyone who stands up to be counted with our enemies. Unless they are willing to fight on our side, give money, give time, speak out, do SOMETHING... they are stigmatized in my book, at least.
