I would say that you're just being needlessly self-concious. In general, people are idiots. I'm particularly fond of a quote from slashdot:

"I often look at people as half a CD-ROM of entropy at birth, then try to apply in my head the 300 petabytes per decade of their life that I estimate is an upper bounds on total sensory input of continious living.

I recommend this exercise when talking to really dumb people."

So, yeah, just roll your eyes and remember that someone who goes by the moniker "3-State Bit" thinks people are stupid, so you're safe in thinking people are really stupid.

(And the games collection is great fun, it was a wonderful stress reliever last night. Thank you!)
