something I have to wonder about the libertarian position on this. If it were not government imposed, and it was a business's private decision to use affirmative action would we still be against it?
You can believe that someone has a right to do something, but still be against it. For example, I believe that one has the right to hold racist opinions, but I am still personally opposed to racism.
I'm just curious about if we would support it if a business decided to do it on it's own grounds.
Libertarianism only deals with their right to do it. Whether you would support it or not is just personal opinion.
