Homosexuals do make the very REASONABLE point that they're sick of having exclusionary heterosexism shoved in their faces from birth, though childhood via texts, readers, films, TV, into adolescence with peer pressure, family pressure, media, music, school 'traditions' and into the job world, on to legal barriers regarding inheritance and even who has the right to oversee your burial.
Forget the political wackos which exist among any special interest. In general, homosexuals want equality in term of respect, human dignity, decency, a libertarian, a sovereign citizen's attitude from their fellow Americans regardless of sexuality.
I'm sick of having the homosexual lifestyle and homoeroticism shoved down the throat of my teenage kid in school, from the media, on television..........
What other segment of the population that is so small forces their agenda on others the way some in the gay community now do? I do not force my lifestyle on others, nor should others expect me to like it when they force theirs on me.
As for the legal aspects, anyone can create a will and leave what they want to whom they want (except for the fact that a spouse cannot be written out of a will), including burial arrangements.
Marriage is what it is. Fathers do not marry daughters, either. Homosexuals can marry ceremoniously, but it is different to expect a state government elected by the people to sanction it.
