5. Legalising same sex marriage poses a treat to religious liberty.

I'm sorry may I ask why is that a bad thing?

I thought this was supposed to mention secular reasons.

Obj 1. That such persons are born with natural homosexual tendencies does not makes it normal.

Actually that makes it more normal since indoctrination of third part influences are discounted.

Indeed, many people are born in ways which we consider unnatural or disordered.

Ohh you're making me blush.

The complementary nature of the sexes sets the standard for what behaviour should be considered normal as far as sexuality goes.

That's both sexists and homophobic.

Homosexuality goes against the complementary nature of the sexes so it should be seen as abnormal.

Obj 5. Allowing same sex marriage would lead to schools teaching that homosexual relationships are equal to heterosexual ones and it would also force taxpayers to subsidize homosexual relationships despite the fact that they are against it.

Okay I'm confused. In objection number three they say that The benefits that same sex couples bring to the economy would not proceed from marriage itself but from their capacity as citizens.. Which makes me think that this study put's marriage above the state, so may I ask why does the taxpayers get to have any kind of voice in this fifth objection that it puts the state above marriage?
