Sorry, but I have heard the liberal refrains time and again.   It gets a little boring after awhile.  Always the same bashing of the white man time and again.  No matter what evil is cooked up, it is blame the white man.   Have you not heard the white man is to blame when a black man kills another black man.   It is the white man that was responsible for 9/11.  it was the white man that was responsible for the death of cops in Dallas.  Yes, I know that there are problems between the races, but it is not ALL the white man's fault.  Many of us are tired of acting like it is and either having our hands being bitten off when we reach out or the demands of more and more. 
When the teachers have something new, I do listen.   But so far, they have not had anything new, so I just laugh.
