People who ask this kind of question almost always have an extremely broad interpretation of disrespect. It's like they go looking for things to be "disrespected" for. Most people aren't disrespecting you.
If you don't like someone's behavior, don't spend time around them and move on with your life. If you generally like it, but in a particular case you feel disrespected, get over it and move on with your life. If it's a coworker or situation where you can't get away, just try to ignore it and focus on doing your job/etc. Respect is highly subjective.
Respect yourself and only do things which are in accordance with your self respect. Let other people worry about themselves.
