Earlier quoted context omitted.
I'm going to take issue with just one statement here because I'm short on time - > special kind of oppressor to tell you ... who you are allowed to love and allow into your family. They don't. You can have a polygamous marriage all you want, you can have an open marriage, you can be as gay as you want. However, husband, wife, father, mother, son, daughter and what not also have legal ramifications, and that is where…
These legal ramifications should be either abolished or applied to everyone who applies those titles equally. Anything else is state-sponsored discrimination and harassment, which is our current sad state of affairs.
You get a divorce from one wife. What does she get?
These are just two things off the top of my head that throw a monkey wrench in things making the 'just abolish it' not quite as simple.
As for 'state-sponsored discrimination and harassment' just no. That is people and their attitudes, legality has nothing to do with it. Blacks weren't seen as equals and without harassment just because slavery became illegal and they could vote. Homosexuality is legal, but again, individuals don't harass based on legal status.
You are conflating legal issues with personal views of morality, they are not the same thing and have very little to do with each other.
