What would happen if the parents of white students in a mostly white school said that a black teacher should not be allowed to teach THEIR children, AND some of the teachers agreed?
Double standards are standard.
It just doesn't happen that often. The strange paradox of public education is that black educators that teach in mostly white schools are there because they are outstanding or at least above average educators. White teachers that teach in mostly black schools are there because it is their first job or they have medorice teaching skills.
Just a generalized observation and I am sure plenty of counter examples exist. If stuck teaching at a public high school the best bet is teaching classes after lunch hour, if you don't mind the stench of marijuana residue. The trouble makers are usually stuporus or lay their heads down on the desk.
