Open Forum: Does Gay Marriage Threaten Straight Identity?

In most progressive nations people support some form of legal recognition of same-sex relationships whether it be civil unions or domestic partnerships, but they outright reject the notion of providing marriage to gay and lesbian couples. Obviously something about granting marriage rights to same-sex couples threatens their world view.

Do self sufficient lesbians threaten the roles of the stereotypical "housewife" and the "man of the house" status. Does this whole notion of women's liberation in the sense that a woman need not be dependent on a man, not only threaten the mans macho self image, but also challenge the traditional "housewife" to reconsider her subservient role?

Do effeminate gay men represent a loss among straight men for their image of male supremacy and masculinity? Perhaps, marriage for these men would be an indicator of acceptance of them, and in order to preserve the "male image" femme men cannot be accepted or even tolerated under any circumstance.

Is there an irrational fear that children being raised by same-sex parents may grow up open-minded or even explorative of their own sexualities. The more homosexual people there are, the fear of a destruction of the human animal becomes a reality in the mind of our critics.

If gay marriage is legal, it will be on par with straight marriage and will be considered just another variation of a legal contract one can enter. Does the fact that one group can put down another help to empower this sort of straight pride and privilege that exists in our culture. Although never discussed and maybe entirely sub-conscious perhaps there is this feeling of being above gay people.

So what do you think, does queer sexuality/identity threaten heteronormative thinking and identity? Could this be one of the reasons for fierce opposition to granting marriage rights to same-sex couples?
