Random things that bug me:
I hate when guys treat girls like they have to be submissive to them, or when they treat them as any lesser than themselves. We're all invariably people, so I think gender should not be a hindering factor in how much respect someone gets, or how much say they have in any matter(s).
I also don't like when people don't respect personal space. People are largely very unaware of where their bodies are in relation to someone else's, and what kind of a message they could potentially be sending.
