1 "Chess has little to do with intelligence."
= Not exactly true. Chess requires thinking, and a type of thinking that you can get better at. If you mean that chess doesn't simply reflect the general mental aptitude of each person, then fair enough. But what does, exactly? What sort of activity is such that it is a strong reflection of a person's general mental aptitude, and isn't the sort of thing you can get better at with time? Are you upset that you are getting beat by people that you perceive are less intelligent than you are? Go play baseball.
2 "Chess causes people to become unfriendly and callous"
= No way. Some of the nicest and most intriguing people I know are chess players.
3 "Chess wastes time"
= If you don't like it enough for it to be a hobby, then don't play it. But we all need leisure. I choose to spend most of my leisure in chess. What form of leisure would you suggest doesn't 'waste time?'
4 "Chess is shallow"
= If you only played because you were addicted to some warm fuzzy, then I can understand why you're leaving it. The only reason I stayed a Christian so long was for exactly the same reason; no substance, just fuzz. But I stay with chess (though she be a cruel and promiscuous mistress) because I find it inherently beautiful. I enjoy the problem-solving aspect, the competitive aspect, the universality of it, etc. If you don't see art in a Capablanca endgame, then it might just not be for you.
And that's completely fine; it doesn't have to be. Something else will be. You said painting; paint, then.

Chess does not waste time, it is a hobby like skiing, swimming arts and craft etc.
You may simply not have the connection to chess, perhaps try checkers the Canadian game.
You play bullit and blitz games only and have very little time to consider your next move.
