To me this kind of language is useless and non-descriptive. A pianist is someone who plays piano, a botanist is someone who studies plants, but a "socialist" is merely someone who BELIEVES in the ideals of socialism, whatever that means now.
Trying to categorize people simply by what they believe, and not what they do, seems useless at best and damaging at worse. Whenever you see political debates now, most of them are just debating whether something is REALLY libertarian/socialist/left wing or whatever.
I feel like there is just a grave flaw in our language. Our language is so mired in abstraction that any action is stripped away. Most words ending in "ism" are, if we are totally honest, completely worthless and cloud rather than clarify thought.
