I'm gay. My partner and I own a house we both pay for, but it's in his name. If he dies, I shouldn't have to pay inheritance tax to take ownership of his house. If I refuse to, since our marriage isn't recognized, I will have others come after me for my money.
I like to grow flowers. Some of them are beautiful, but were deemed dangerous and banned because others use them to make drugs. I can't grow them, because I'll risk having my door busted down, even though I'm only interested in the flowers.
I like to travel, and do so a lot. Neither I, nor the airlines, want to put up with the idiotic taking off shoes and not carrying liquids rule, but both of us are forced to comply with them.
I wish to hire someone to do some web work for me. To do so, and pay them legally, I have to report whom I'm hiring, fill out forms, and pay a variety of taxes and insurances, even if it's just a temporary contract work. If I don't do this (and most people don't), I risk getting in trouble with the government.
Plus there's the issue of my tax dollars going to pay for things like police arresting nonviolent drug offenders and giving them food and housing for months, or going to pay for military that at times tends to kill innocent civilians with no repercussions, both perfect examples of aggression being initiated unjustly.
But if you were to rent, would you complain that part of your rent payment goes to property improvements you're not interested in? Would you complain if the landlords said 'no pets'?
Move to a gay friendly state. Kind of like moving if you don't like your landlord.
