Ben Shapiro's article, "The radical homosexual agenda and the destruction of standards," provides a powerful critique of the flaws in the concept of "tolerance." They basically boil down to the fact that the immoral and amoral are never satisfied. They keep reaching new lows, and insisting we accept those. They keep insisting that I not only allow their behavior, but accept it as normal, as good, when I believe it harmful and bad. They demand I accept them and their beliefs, but do not accept me or mine.
Actively homosexual people should not be discriminated against. Well and good. We can agree on that. But their behavior is not normal. It is not healthy. It is much like smoking, a poison that will kill them given time. Kill them spiritually if not physically, and often enough both.
I am not discriminating against them when I deny them the ability to marry another of the same sex. I am recognizing the reality of marriage. It simply is not possible for a "marriage" between two people to be, in fact, a marriage. I am not discriminating against them, nor against single parents, when I say that ideally a child is raised by a mother and a father who are married and who have been married to no one else. People fail, they are human, and so some couples end up divorced, and surely those families, headed by single mothers and single fathers, need our prayers, assistance, and support. But the ideal remains: ideally the family would not break down; ideally children would not be abused by parents; ideally they would not be abused at all. Ideally they will be raised by a loving father and a loving mother who teach them right judgment, good morals, a strong faith, and a strong work ethic. And society would be better for it.
