Well, I did think everyone would encourage suicide of pedophiles since pedophiles are so bad for society, but most people dont for some reason. At least not here. I dont know why.
Peer pressure.
People on DART tend to have higher IQs than non DARTers. Low IQ people are easily susceptible to peer pressure (with that comes caring about their reputation and fitting in).
It is socially taboo to encourage suicide and to support pedophiles (defined as respecting their right to life). I ran an experiment with 3 people who I know are low IQ. I asked them if someone was considering suicide, then what would they do? They said they would want to get that person help. I then asked, "What if that person is a pedophile?" They couldn't respond because they didn't know what was socially acceptable to say (prevent suicide or to be sadistic to pedophiles).
People on DART are more likely to have higher IQs and therefore, are more willing to be an ideological minority on an issue they actually believe in.
