Of course your opinion can be more or less helpful than another's, depending on what you say, how you say it, and what your sources are

Well, by no means am I trying to shut you down, I'm doing the opposite, asking for more details. For example another comment on this thread pointed out that apparently Republicans usually sign some kind of "loyalty oath" that's associated with him. I would consider that strong evidence for his association with traditional conservatism.

If you check that part of the thread again, you'll see that that "loyalty oath" is associated with Grover Norquist rather than Thomas Sowell (although I'm fairly sure Sowell also thinks that taxes and government expenditures in the U.S. are way too high).
