Yep, socialism is a definite -ism, Keith. A set of tenets, principles and aspirations. Not an undeniable phenomenon of nature, like evolution. Which is why evolutionism, whilst a perfectly real word, is not the right one. Evolution is a natural phenomenon with a rather good theory for explaining it. People who specialise in its study do not regard evolution as a set of beliefs. Those people are termed evolutionary biologists. As ever, you always side with the wrong people. It's quite instructive that you now have pete on board. I'd hate that if I were you.
