Then I pity you, my friend. Would it be "okay with you" if they decide to become alcoholics? How about heroin addicts? Or necrophiliacs? Just more alternative lifestyle choices, right?
You can have all the Judeo-Christian culture you want in your own homes and churches.
Not for much longer. Pretty soon people with your sentiments will be locking up us "hate criminals" for what we do in our homes and churches.
Besides, it's not "culture" unless it's public and common to the majority of the population.
But the government is not your private goon squad for the enforcement of Christian morals. At least not anymore.
In general, the goon squads used to enforce the common morals of Western civilization, not specifically Christian morals. Some communities had laws that were specifically based on Christianity, true, but most laws enforced by the goon squads were based upon common-law restrictions on behaviors that were considered evil by people in all Western cultures -- you know, things like murder, rape, sodomy, and so forth.
But you're right -- we as a society won't enforce those laws anymore. The New Order has come swept away those tired old relics of a less-enlightened age! Behold, all things are made new!
But the goon squads remain. The question is: whose morals will they enforce now?
