I just feel it's totally natural to want to be with like-people and to be wary of "others". I think we're hard-wired to feel that way. It can also be a protective mechanism to make connections of people who are like the ones we've had bad experiences with.
We fight instinct so hard, as humans. Would it be best if we could all get along? Of course! I'm just saying that there is more than one reason for shying away from certain people/groups. And I don't believe that if you give someone a job and money, and be nice to them, that they will turn around their bad behavior. Some yes, but others no. And I feel this group is growing and getting away with bad behavior.
My feelings about this are because of my own personal experiences throughout my life, and what is happening every day in the city near here. Just remember........I voted for Obama twice. (But I'm sure that will elicit put-downs too).
