I agree with this to a degree. There happens to be a Lord of an area I will not name, but for sake of argument, I shall call him LoWe. LoWe owns some very valuable property in the UK all of which was given to him for free through inheritance because as with all Lords born into it (and not brought it from Labour) at some point a King fancied a bit of a married woman and should her husband turn a blind eye would get much land.
Many years later that land is now highly valuable and makes LoWe worth hundreds if not billions of pounds and yet he only has to pay the same tax as someone on 20k a year because he can afford to employee an accountant who can fiddle the numbers enough.
That is unfair and should be stopped, but it hurts everyone in power so never will be.
For you to live like that does not require legislation though. I find the whole concept of marriage pointless and only there because some guys writing a book thought it was a good idea. But I shouldn't then have the right to demand no one gets married because I don't like it. Personally I am not a fan when the homosexual couples at uni used "breeders"* as a slur, but I just see it as proof that bigotry and hate runs both ways.
In the same view I have no problem with same sex couples having all of the same rights as opposite sex couples. That doesn't require a law to make me think that, it is just the way I roll. By removing the state from our personal lives all together a lot of the bigotry will vanish (given time, it isn't going to happen over night) as most of it just stems from laws/culture being formed around a badly written old book.
* Context: We were organising a night out and a few of the people I lived with were in same sex relationships so they naturally invited partners and friends. While sitting around waiting for people to turn up a group of said same sex couples were going on rants about how it is breeders fault the country is in a poor state, so much crime, etc. it is just nature for people to hate everyone that isn't in their little tribe. You can't expect the gov't to protect your feelings so you don't get hurt.
