Interestingly, even the "step father" isn't married to his mother.
I think a lot of the protesters and rioters have been raised with no father or other authority figures present in single parent or no parent families. Some of these so-called families do not mention or explain why their members have different surnames and relationships or if a marriage is present.
Hillary has advocated "it takes a village to raise a child", not a two parent family with a mom and dad in a normal loving caring authoritative relationship. Having down played these benefits of a real family and negated the responsibility and accountability of a father to raise his children to be productive members of society, one is seeing the product of what we used to call "the broken family".
Finally, the government has tried to replace the lack of the family through welfare and other programs which has led us to where we are. No wonder these people protest, riot, and rebuke authority. They never received the love, values, and other benefits a real family can provide.
We are rapidly becoming a society composed of broken families. Which is why our society is in an a breakdown mode.
