You are relating a history there Professor.
So you accept the history of humanism then Vlad - a ethical philosophy that has existed for far longer than christianity - that has demonstrated greater universality than christianity as it has sprung up independently in places as diverse as Greece, China, India and the Americas.
But we are where we are......Humanism UK, the atheist movement.
You can't even get the name right can you Vlad. And HumanistsUK never has been, nor is currently and I suspect never will be the global arbiter of humanism.
There are Christian Socialist organisations - does that mean somehow that all Christians must be socialists and that all socialists must be Christians.
