WHAT'S WITH SPITTING

I was watching the baseball game the other night and was disgusted at the players continually spitting. Every time the showed a player he was spitting. Is this a baseball thing? Do the kids in Little League do the same thing? As role models, this is not teaching the younger generation good hygiene or manners. Football players grab butts, baseball players spit. I don't know which is worse. These are just my thoughts, maybe yours are different. I hope not.
