How can I get my parents to see that social interaction and fun are irrational ? I have other things to do?

I think you sound a bit odd, but if you want to be that way, then be it. But don't diss social stuff, it's more important than if everyone just observed and made notes. We need to meet and make friends for us to talk and fall in love and do anything. You are reaching out to people here, maybe you are too shy to do it in real life so hide behind being clever and thinking you're better than others.
