That's another argument.
Don't you see? You can't attack her argument for it's application to other issues. You have to attack her argument for it's own sake.
A perfect example is what liberals do with virtually everything they touch - they invoke the magic "could" - "This could lead to that, so it needs to be banned." "That could lead to this, so it needs to be banned." Think of what the FDA, and the EPA, and all the other agencies do with this on a daily basis.
These aren't trivialities. They're the WAY the Left wins things. And by not dealing with them properly, conservatives win the morality game while losing the political game. And look around you and see how well that's worked.
Note - I'm not saying anyone needs to loosen up on any beliefs. Rather, I'm saying people need to give the same level of discipline to the proper expression of those beliefs, as they give to the beliefs themselves.
It demonstrates the stupidity of her argument, which leaves her conclusion in doubt. By her reasoning, anyone can marry anyone or anything if they just 'love it'. And that is ridiculous. You cannot marry a cheesecake.
50 years ago, no one thought homosexuality would be legalized, let alone given honor by the government. There was a time, long ago, where no open homosexual could hold public office.
Two guys sharing a house isn't my business. Two guys claiming their 'love' is of equal value and worth in the eyes of God and the future of the country as heterosexual love is a huge problem.
God will not be mocked. If America doesn't repent, America will face the rightful wrath of God.
For someone who has claimed to be a follower of Christ to publicly reject the Gospel - which starts with repentance - and proclaim evil is good, IS my business:
"In my previous letter I said, “Don’t mix with the immoral.” I didn’t mean, of course, that you were to have no contact at all with the immoral of this world, nor with any cheats or thieves or idolaters—for that would mean going out of the world altogether! But in this letter I tell you not to associate with any professing Christian who is known to be an impure man or a swindler, an idolater, a man with a foul tongue, a drunkard or a thief. My instruction is: “Don’t even eat with such a man.” Those outside the church it is not my business to judge. but surely it is your business to judge those who are inside the church—God alone can judge those who are outside. It is your plain duty to ‘put away from yourselves that wicked person’." - 1 Corinthians 5
