Well, to be fair, at least some of them are self-declared Ron Paul supporters. Funny thing, though, I didn't see a single post from any of them on the MTV LIVE debate thread that's in the breaking news sidebar. Ron Paul was one of only four participants, too. I guess they weren't interersted in watching their candidate debate. Yet, they were online the whole time, camped out on this thread. Hard to know what to make of that...either it's not true that they're supporting Ron Paul, or it's more fun for them to bash Romney supporters than to support their own guy, or they don't like to be on Paul-centric threads because too many FReepers make fun of them.
At any rate, I agree with your characterization and your suggestion to ignore.
If you ignore them, they will probably get bored and look somewhere else to feed their little egos.
Or, gosh........maybe there's just no access to a hooked up t.v. Just d@mn. Guess you don't have everything figured out, do ya?
