The problem is that it doesn’t stop with marriage. You are correct the fight began to be lost with losses in other areas. Losses against pornography and having it defined as “freedom of speech” helped set the stage. The radical feminism and the free love movement of the 60s made the transformation we see possible where it would never have had a chance in hell before. While some of the influence has waned for “feminists” they essentially achieved their goals in that most families if they are working families have two parents working almost exclusively outside the home for proportionally the same income and lifestyle that one parent used to be able to achieve not only do both parents work outside the home but they also often pay for single mothers through taxes to stay at home while the govt pays for those mothers to send their children to free daycare. So homosexuality and ssm isn’t the beginning of the fall the fall started long ago as common ideas about the family structure and decency were eroded.
Those that are apathetic need to wake up and start making themselves heard because the next phase coming is going to be even worse and strangely it appears too many of our neighbors are just fine with enabling the thought police empowered through govt to root out “homophobic bigots”. I wish that I could just unplug and not care. I could probably live the rest of my life and avoid the worst of it for me and my family but that would be a surrender not fit for anyone calling themselves a patriot. These are “fights” and our opposition most certainly looks at them in that light and its about time apathetic conservatives do too.
I believe the best approach in times like this is to be principled in your thought and virtuous in your conduct. And to always do these things with an air of serenity and a smile on your face ... even if circumstances require you to deal with someone through the sights of a loaded firearm.
