The fact that your asking implies some insecurity.
I'm gonna have to stop you right here (read: didn't read the whole post because this sentence told me all i needed to know)...
what evidence do you have for this being a sign im insecure, as opposed to just curious? it could be possible my intelligence is verified constantly in real life and i'm just wondering how the way people view me differs here and want to compare. what you said is not the only possibility. so what are you basing my insecurity on?
