What is reverse discrimination, and do you think it is possible to prevent it while still protecting the rights of minority groups?

Reverse discrimination is basically the practice of minority groups being unfair or discriminating against majority groups. I think that it is completely possible to protect the rights of minority groups while preventing reverse discrimination because we can all just come together as people instead of different races etc... we should all be judged and given based on merit since we are all humans and this would of course work if nobody cared at all about minority or majority or race or sex or whatever...
