"You are, and you don't even realize it. That's pretty much the point of promoting diversity."
Diversity of ideas is good - more people with different ideas make it more likely that a viable solution will be found, and if those ideas can be shared and discussed without fear of repercussion then they can complement each other and the sum will be larger than the whole of its parts.
However, forced diversity based on any racial, religious, political, or sexual criteria is bad. It discrimination and bigotry in pure form.
When someone says that the way to combat discrimination is WITH discrimination, all I see is a hypocrite.
