Does Downgrading Others Earn You Respect?

How can you be a show off and still expect to be respected or liked? Sorry to say but you know those peers who tolerate your attitude it’s not because they like you or respect you but rather because they have their own selfish insecurities leading to them tolerating you. How is it hard for some to just be satisfied by minding their own business and not feel the need to downgrade other to feel good about themselves. Are you that desperate to see yourself value/worth through the lens of downgrading someone else? Is that where it lies..by being mean disrespectful etc?
