Small Lore related question! [Races/Culture]

So, in this campaign, I made an Avariel. I'm very new to all things DnD/Pathfinder/etc. and it was explained to me that most if not all elves are kind of.. really racist.

When I was reading the races book for Faerun and read the Avariel section, I recalled it basically saying "they're racist assholes, but figured out that's a bad thing and they're trying to stop."
Our party consists of two humans, a werewolf, and myself.

Long story short, I'm not sure how weird/awkward of a question this is: But what are some things my character might think or say in regards to other races that are kind of dick things to say, even though he might not realize it?
