We have this thing called diversity policies, and some people agree with it, and some people disagree with it. The people who agree with it are free to present arguments about why workplaces are discriminatory and why diversity is valuable. But with this - I'm starting to wonder if the same is true for the other side. Are people free to post counter arguments showing that lack of diversity may be due to other factors such as difference in behaviour or tendencies? It doesn't appear that way.
