Dont you understand why it seems that race relations worsened? Think... when else were race relations really bad, when did they spike? During the civil Right she movement... when all the crap was brought to the surface.
Because lefties have been screaming racism ever time some republican engages in partisan politics.
THis divides the nation, between blacks who feel increasingly under attack, liberals who are outraged by their false perception of racism, and republicans who are increasingly sick and tired of being vilely slandered by assholes.
You got half of it right, extremist on the left do play the race card too much... but you ignored the other half of the equation that exisists in the "Rights" denial and neglect of racial issues. In many instances, when one is brought up from the left, the right argues against it and denys the problem. For some reason the Right takes on an advisarial roll in most race related policy the Left tries to pass... when was the last time the Right lead the charge on a civil rights, pro immigrant, LGBT, or anything aimed at helping the African American community??
That is because by and large, legal equality has been achieved and what passes for "Civil Rights" today, is actually reverse discrimination.
YOu are aware of the studies demonstrating a 230 sat point bonus for having black skin in Ivy League University addmissions, for one limited example?
The problem with you're attitude is one of two things, maybe both... either a straight up denial that racism still exists in our society or an ignorance to racial effects of history. In a country with a history of slavery, oppression and white privelege there is an inherent advantage to the white race, generally speaking. A significantly larger portion of white citizens have come from generations of wealth, higher education, and social influence that provides better opportunities. Not to say there aren't plenty of white workers who grew success from nothing... but if you look at whites compared to other minority groups you have a dispropprtiaonal transfer of wealth, privelege, and opportunity.
The black community has been trying to grow from nothing since the days of slavery, and the struggles have been long and hard, fighting discrimination in the workplace, social bias, and the cultural disadvantages that permeate through community's of poverty, high crime and low education.
So you have whites that come from higher class property and business owners compared to blacks that come from a history of oppression, poverty and lack of education.
You are right that legally we have done some great things to even the playing field, but we can't ignore history and it's effects. This is where the Republican Party is missing the ball. They tend to deny or argue against what I just stated. If they showed a basic understanding, consideration, and acknowledgement of the imbalance it would go a long way to bridge much of the racial divide that exist in our society.
