My point is, you're being extremely narrow-minded in your assessment of communists. "All these Communist regimes have killed so many people therefore it's all bad, and all communists are stupid and they all need to be rooted out and we need to fear them." That's bull****.
You're a religious person. So many people have died because of religious strife. Would I be correct in condemning all religion as evil, and all religious folk as a blight on society?
