"..."Communism" says: religion is the opium for the people." How can communism be a religion?..."

Communism is a kind of religion because it has its own principles, its own ideologies, its own moral values its own books its own leaders...similar to any world religion.

For example:

just like religions have messengers and prophets similarly for communists we have karl marx and lenin;

We have their symbol: Red flag, the hammer and sickle, raised-fist salute tec.

Rituals: March-pasts. Conferences of the single party

So we can find similarity between religions and communism
