Which ones is it insulting to?
Marx gave rise to an ideology that Stalin used to impoverish and kill millions of people. The not-death of Christ on the cross led to the potential for the salvation of us all according to Christian doctrine as I understand it.
I'm trying to say that religiously, I do believe in Christ, and I think the use of Marx, Stalin, etc in the same sentence is a bit insulting. Marx and Stalin created a belief system that was used to enslave and kill millions. Christ came to save everyone. To some extent, Marx and Stalin knew what they were doing, so did Hitler. The Pharisees were misunderstood and feared their power, they too are like Hitler and Stalin, but for different reasons. The others, even Jesus had said they did not know what they were doing. He forgave those who betrayed him and those who sent him to the cross because they did not know what they were doing. So yeah, I guess I thought that they were saying that Stalin and Marx were the ones crucifying Christ, thats where the insult came from.
