Did diversity build and sustain America through world wars and economic challenges? No, it was a firm set of principles held by patriots of many races who were willing to pay the price in money and blood. These days, we seem to be increasingly confronted with people who are the political equivalent of shoplifters: they want the benefits without paying the price.
If you are unwilling to part with the money you earned while building a business, or a life, to fund a life for others who refused to do so, are you selfish? As a way of punishment, should your hard-earned money be given over to those who didn't earn it?
If you have a particular faith (Christian) you are to be discriminated against and silenced. Your sacred symbols -- from crosses on a desert mountain, to Nativity displays in public places -- are banned. You increasingly are forbidden to pray publicly "in Jesus' name," but Muslims can speak of Allah and Mohammed anywhere they like and who is foolish enough to try to silence them?
Apparently, "diversity" is not for everyone and even if it were, what does it mean? To those who wish to impose it, it seems to mean that no one can any longer speak of truth, or even seek it out, because according to the rules of diversity, there is no objective truth. Thinking so makes you a fundamentalist, unless you are a fundamentalist Muslim, in which case you are to be accommodated, pacified and given special rights -- like ritual footbaths, prayer rooms and prayer times at public schools and universities that would probably be denied and challenged as violations of church-state separation if a Jew or a Christian were to make requests unique to their faiths.
I grow weary of having to tolerate everything when none of those making such demands seem willing to tolerate much of what I believe. Shouldn't diversity be a two-way street instead of a roadblock?
