I will not heed the call to abandon MY culture in the name of "diversity".
I will not sacrifice the pursuit of excellence for the faux god of making someone feel more adequate.
We became the greatest nation on Earth because of the pursuit of high standards. Sacrificing those standards would only make us like everyone else. If those crying because they either lack the ability or the will to put forth the effort to meet those standards, there is a world full of smaller ponds where they are welcome to go swim, where despite the laws of physics and nature, less will get them by.
If you want to be the best, you have to work at it, constantly. You don't get there by pulling others down, it isn't just a relative thing, you meet the standards, you match or exceed specifications. Otherwise, your plane won't fly, your rocket will blow up on the launch pad, your crop yields will be down, your people will starve. Mother Nature doesn't give one whit about "diversity" in a cultural sense, and she can be a mean mother...
