Not only do I simply "not want to get married", I think that the gay community does itself a disservice when it attempts to conform to heteronormative and traditional ideals of what relationships should look like in order to be considered valid by wider society.
It is my opinion that gay people can protect themselves financially and give themselves the same level of rights and security by using civil partnership which is a perfectly viable option that isn't rooted in ownership, conservatism, tradition, religious belief and is, in my opinion, an outdated institution no longer compatible with modern relationships, including homosexuality.
My issue with marriage is not the sex or sexual orientation of those within the union, it is with the institution of marriage itself.
I understand that there is a lot of pressure within the heterosexual community to marry because it is often linked with finances, this can be evidenced by the number of mumsnet threads about "he doesn't want to marry me, my high earning DP is avoiding talk about marriage, he doesn't want to commit even though ive washed his pants for a decade, my DH doesn't lift a finger and i'm unhappy but I cant leave because we're married, DH has been abusive and I want to leave but hes emptied our joint account behind my back and i'm scared about divorce" etc etc, and upon reading this I have no idea why gay people wish to engage with or link themselves to such an antiquated system that appears to be particularly designed to oppress women into domesticity in order to formalise their relationships.
If they just want to do it because it's their right and thats how they want to formalise their relationship, thats fine.
I have absolutely no inclination to remove the right to from ANYBODY, gay or straight, and im more than capable of understanding that it may be what other people absolutely want to do for their own reasons within their own relationships, but my thoughts on the matter run much deeper than "not wanting to do it", to the point that I am actually pretty against it.
Hope that clarifies.
