I agreed that families have a strong impact, which is why we eat dinner with our kids every night and used to read to them before every bed time. These are two things that were primary commitments in our household. I disagreed with your belief in some golden age when families were perfect. If schools are teaching only "safe sex," as you pejoratively describe it, that's not "comprehensive sexuality education." 

Our nation was built on traumatic family destruction. We freed ourselves from Europe through a slave trade. https://opinionator.blogs.nytimes.com/2015/04/03/how-the-slave-trade-built-america/?_r=0
We had upstanding leaders for whom I have deep respect (Thomas Jefferson for one), who owned humans, conceived children with slaves, and raised those children as slaves. How sick is that? The grocery story incident pales by comparison. Hooded figures in the Jim Crow south terrorized families and lynched innocent black men. Sick. Miscegenation laws were stricken only recently. Sick.
