There are definitely a few dominants out there with inferiority complexes. Just watch for the chest beaters and the ones that routinely get involved in dick measuring contests.
Do I have a superiority complex? A bit of one, but it's one that's backed up by science. It's also not something that you'll see day to day because I recognize it and behave like an adult (regardless of what I think of you peons). This does give me an opportunity to release that side a bit and is cathartic in that sense. However it is hardly the only, or even the primary, reason behind my desires.
