i'd be interested in what "tolerant qualities" the right has.
This will be generalizations as I see it but accurate in general in my opinion:
Lefties tend to see things through a racial or gender prism. When lefties think of minorities they think that its oppression of them that has led to their tendency to be low income, less success, higher crime, etc. In other words, they believe that the only way minorities can succeed is to end this oppression. That means whites (the oppressor) has to change something. By extension, minorities must be helpless to that fact. Top that with the constant equivocation of one aspect of human characteristics with another as being on the same moral level, the only differences between anyone in life must come in the form of bias or discrimination. They also define tolerance as not just putting up with your neighbor but showing dislike of your neighbors activities is a sign of bigotry/racism/homophobia etc.
Those on the right tend to put individual merit above all else, they don't factor in race nearly as much. The notion that minorities are in a worse state overall isn't a sign of oppression, its a sign of a lack of effort or repeatedly making bad decisions or a culture that doesn't emphasize the right values. That lefties tell minorities repeatedly that they are powerless is a detriment to minorities because that means they are absolved of having to try. They don't see all cultures as equally successful. The differences between people in life come from whether their decisions were sound or not. They define tolerance as putting up with your neighbor even if you hate his guts, disciplining them if you can, but not blowing them off the map.
I tend to agree with the right's outlook, obviously, not that there aren't problems with it. Racism does exist but its not as big of a problem as its made out to be. Some people do have a string of bad luck and some have it so much that they might need welfare, but I'm of the opinion that most people on welfare aren't having hard luck, they're trash individuals. The existence of successful minorities like asians flies in the face of the racism explanation. And political correctness surrounding racial issues assures me the problems will never be recognized, let alone fixed. When blacks accuse other blacks of 'being white' because they got an education, dress respectfully, and speak eloquently I would think thats a problem, but can't talk about it without being accused of racism.
This is not a full spectrum view of what people believe, but I think I've adequately explained why the notion that one is more tolerant than the other is bogus.
