Michael Brown was a criminal. He was not an innocent victim. Fewer Michael Browns equal safer communities. You can't ask for safer communities and then defend the criminals that terrorize those very communities. You cannot demand better policing of those communities and then protest when the police take out a criminal in that community. Sends a mixed message. You either want a safer community or you don't. Safer communities mean the Michael Browns of the world end up dead in the street, or in a jail cell. That's a good thing and until the left gets it through their heads that it is a good thing the violence in those communities will continue. Frankly, it's what they want. Keeps the perpetual campaign issue on the table.
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.
