The snowflakes have been bleating aobut the wonders of "diversity" ever since I can remember. However, it's actually a big lie, in the Goebbels sense of the term. Here's an interesting article that explains why it's bullshit. We don't benefit from immigration. We are positively harmed by it.
"Diversity is a strength” is one of those Orwellian maxims that’s just generally accepted as truth by most Americans despite the overwhelming evidence to the contrary.
Granted, if you’re talking about a DIVERSITY OF IDEAS, you can certainly come up with some situations where it’s a strength. For example, in the movie World War Z, Israel is saved (at least temporarily) by having a “tenth man” whose job is to forcefully argue for the alternative viewpoint to a situation where everyone agrees. So instead of laughing off the idea that Israel might face a zombie invasion, Israelis realized there was merit to it and was prepared in time to protect the country. Back in the real world, the NFL certainly could have used someone pointing out the potential long-term downsides of allowing players disrespect the flag when just Colin Kaepernick was doing it. Donald Trump might benefit from a diversity of opinions when he’s about to tweet about Rosie O’Donnell or Mark Cuban at 4 AM. The Democrat Party could certainly use the input of a few random white factory workers from flyover country about the latest rhetoric and proposals they’re about to pitch.
On the other hand, even when diversity of thought is useful, it’s only in limited doses. The New York Yankees don’t want players who think the Boston Red Sox should win the pennant. A Republican President doesn’t want a Democrat in his Cabinet who will undermine him at every opportunity. Our military doesn’t want soldiers hoping the other side will defeat us in a war.
All that being said, when most people talk about “diversity,” they don’t mean a diversity of ideas. They believe a Hispanic guy, a black guy, a transsexual and a woman bring something to the table just by virtue of their race or gender.
This is seldom true.
For example, it is true that a group of white economists working on tax policy could benefit from having Thomas Sowell come out of retirement to join their ranks, but that’s because he’s Thomas freakin’ Sowell, not because he’s black. An all-Hispanic baseball team would benefit from adding Mike Trout to its roster, but it’s because he can play, not because of his white perspective. An all-female start-up would be lucky to get Bill Gates on board, not because he can mansplain things to them, but because he has lots of friends with infinite amounts of money who might invest if he’s on board.
In fact, diversity is often a huge minus. The new black employee may claim you discriminated against him, even if he’s fired for legitimate reasons. The woman may sue for sexual harassment after seeing a swimsuit calendar on some random guy’s wall. The Satanist you hire may call it religious discrimination if you don’t offer him a goat to sacrifice to Lucifer on Halloween.
Diversity can work just fine, but only if there’s strong pressure on people to assimilate to the existing culture. That’s why our very diverse military functions so well. However, we don’t have those conditions in America as a whole. Instead, we have liberals promoting tribalism and grievance mongering non-stop. In other words, every racial, sexual and religious difference is used as a way to split people further apart. Many of the same people who claim diversity is a strength will also tell you white people can’t understand the concerns of black Americans, men are oppressing women and women who don’t want to share a bathroom with a transsexual man are bigots.
You're quoting a blog which uses an example from a television show about a zombie apocalypse to make political point about diversity???? Are you really that stupid??
As for Republican Presidents having Democrats in cabinet, and vice versa, it happens all of the time, and quite successfully too, going back to George Washington and continuing to President Obama.
