You dont have to like something that someone does, but for them to actually do something deserves Respect.
For example, many people don’t like Justin Bieber. Just because you don’t like his music, that doesn’t mean the kid earns respect. Many people aren’t as talented as him and they don’t respect him. I’m not saying I’m a fan of him (which I’m not) but Respect him for the talent he has.
Another Example, many people hate on famous sports players. Just because they are not your favorite player or on your favorite team gives no reason why to disrespect them. They are in the major leagues for a reason, they are talented. Respect that.
