Wow. This could get spicy.
First, I think it's impossible and misguided to say that blacks, or any other group for that matter, complain too much etc. It's just way too broad of a generalization to make without some kind of data. I know it's not your intent to say all blacks act one way or another, but unless you name specific people and specific actions then you're headed down the wrong road.
Second, I think we need to keep in mind the things that blacks have been subjected to. Blacks have been terribly mistreated as a group for most of this nation's history. I think America has made a tremendous amount of progress in the last 50 or so years, but we can't expect blacks to completely forget the past. It takes time for those wounds to heal.
I just recently began a thread of Al Sharpton and his latest antics. I have no problem with calling a specific person out for a specific action. We can't make progress calling out an entire group of people though. That's not fair.
Woodrow Call: For all you know it invites people to rob us.
Gus McCrae: Well the first man comes along that can read Latin is welcome to rob us, far as I'm concerned. I'd like a chance t' shoot at a educated man once in my life.
If I find,
If I find my own way,
How much will I find?
