Often in our public discourse (or national conversations as some people put it), Progressives confront long established social conventions and institutions with the question, "Why?"
Implicit in the question is the idea that once it is asked, then the presumptive legitimacy of that social convention or institution suddenly evaporates. The burden shifts to the conservative justify the existence of such conventions and institutions, no matter how long standing they may be. This mindset manifested itself most recently on the issue of same sex marriage.
Progressives have asked "Why?" about many social conventions over the last few decades.
"Why do make securing a divorce so difficult?"
"Why do we criminalize adultery?"
"Why do we criminalize non-marital sex?"
"Why do we criminalize prostitution?'
"Why do we criminalize homosexual behavior?"
"Why do we forcibly remove illegitimate children from birth mothers who cannot afford them and put them up for adoption?"
Today the rate of divorces is 50% of the rate of marriage.
Today the incomes of divorced women are only 2/3 of the income they had while married.
Today sexually transmitted diseases that once were nearly eliminated in this country are epidemics.
Today over 50% of births occur out of wedlock.
Today we have a more or less permanent underclass that has become a nursery of ignorance, drug abuse, crime, and financial dependence unworthy of any citizen in our republic.
