Recently i was trying to get a small group to join a bitcoin faucet.
(best place to start for those with little money, but much time)
Well, they said that bitcoin was only used by contract killers and drug dealers
and that they liked the govern-cement to be in charge of the money.
And that they wouldn't listen to anyone (like me) who has obviously drunk the Koolaid.
oh well.
There is a calling someone stupid.
Most people have an IQ with one std deviation of the mean.
So that most people are neither much more intelligent nor much stupider than the average.
However, it is this group that calls people stupid for not agreeing with their ideas.
The really intelligent people can see multiple views, and know how ignorant they have been in the past.
Thus, calling someone stupid is just a lashing out and a showing what they themselves fear the most.
