It does get complicated if you want to slice and dice every word and attempt to read minds. I will concede that using a term to identify a sub-group when that term used to be, and still can be used to identify an entire group can be problematic. I'll work on it.Which this time you manage to address without resorting to mentions of race or color, which is a step forward.
It is not my task to evolve you. But you insist that because you are a "liberal", you are not a racist. This is not, however, the case. Granted you do not sink to the level of the rabids like der and max and club and todd and so forth. But you are a racist, nonetheless.
There are, unfortunately, two types of liberals for this discussion. One is the liberal who takes the traditional view than it is up to the liberal to protect the rights of those who cannot do so themselves, hence the regulatory apparatus: clean air and water, airline and auto safety, safe foods (or at least safer than they would be otherwise), and so on. He believes that given a level playing field, the individual can take care of himself.
But there is also the type of liberal who believes that it is the job of the liberal to "care for" the disadvantaged, the underprivileged, the whatever. This is essentially the same attitude adopted by many slave owners during plantation days, e.g., the "Dixiecrat". It is, however, racist, considering the cared-for to be deficient, defective, even subhuman (three-fifths of a white man). And it is due largely to the inclusion of both under the "liberal" label that has retarded our progress over the last fifty years.
It is not the task of the non-bigoted to instruct the bigoted. However, it is incumbent upon those who do not view those of other colors or races or ethnicities as inferior to call out these prejudices when they see them rather than just "let them go", whether in serious discourse or in passive-aggressive cartoons and jokes. It is only by exposing this closet racism that there is any chance of improvement, as with the Jews in the 50s.
Everyone, or most everyone says that would like less reference to race, especially those that are politically motivated. These very same people will then breakdown the vote by race, gender, class, education, etc., etc. They will breakdown employment figures. They will breakdown everything about us using these labels and categories. Until we get past that I find it highly unlikely that race will not be a major component to the discussions we have. I would suggest a good first step for all of us would be to not label someone a racist simply because they disagree with another's position on some subject or idealogy. The conversation goes downhill rather quickly when that happens. The cynic in me thinks that this is not by accident, especially with regard to the body politic and their media hacks.
