Haha pretty interesting comparison but I think it works quite well. Haha but it is not a hard comparison to make as both suffer from the same problem that cause this problem... they believe their reality to be true and unfortunately they enabled by those who also agree with them. Guess you could call it being blinded by passion and arrogance.
At least with the fanboys though they aren't going out and protesting soldier's funerals. That just always gets me mad when I hear about people doing that. But I definitely agree with the last sentiment... they all give the rest of us a bad name.
