A bunch of people who consider conservatism to be all about immigration seem to have latched on to cheese as some sort of protest about the (in their eyes) watering down of conservatism or this site. I think this was the start of it.
Or possibly, a freeper named OWK once tried to sarcastically make the point that an article was irrelevant by replying to it that he likes cheese.
Next he will probably want to know what OWK means, didja ever think this guy might be a double agent and you have handed over the cheese to the kingdom, sheesh!
Typically said to a Democrat --- "Would you like a little cheese with your whine?"
