I'm inclined to think these types of questions contain no real philosophical merit and are simply semantic debates. To that end, they will generate no single "real" answer unless the OP specifically defines "philosopher" in the body of his question, but upon defining it he/she should then be immediately aware as to whether X person fit their definition.
We also have the question: Is everyone considered a "philosopher"? which seems to cover all of X people (the question is borderline philosophical as well). But based on our current practices and policies I am tempted to close these types of questions and refer people to the question above (or make a new Community-Wiki reference question), however I wanted to get input from the community first.
What do you guys think?
