Government is an agent of society. Government recognition of homosexual relationships is about society accepting homosexual relationships as equal to heterosexual relationships.
This is false. Heterosexual relationships are more important to society.
Society also consists of homosexual couples that want to get the same legal benefits as heterosexual couples. According to your argument, since they're a part of society, they deserve to be heard. Not that I'm accepting your argument, in the first place, but it falls on itself.
Homosexual relationships = heterosexual relationships legally. You are free to socially assume whatever you want.
Please define clearly in what way are heterosexual relationships *legally* superior to homosexual relationships? What is the *legal* societal benefit of banning them (not because you think it's icky)
Every argument used in favor of same-sex marriage can also be used in favor of human-parrot marriage. The only difference is that you don't have a problem with bestial-sexual bigotry.
If marriage cannot discriminate against sexual minorities than how can you oppose such a redefinition of marriage?
And as for imbecilic arguments why don't we talk about the same-sex marriage supporters who believe that citizenship status is important for marriage, or that 2 men can procreate together.
No they can't. Parrots are not persons!
Like is said before, if the Church of Nehalem blesses bestiality unions, go for your human parrot marriage. Just don't expect the Government to provide benefits to non-persons.
I've no idea who advanced those arguments. They sound imbecilic they way you've described them. But since you're also seriously proposing legal benefits for parrot-human marriages I will take your assertions with a grain of salt.
