In what particular? I just turned your own argument against you.That's not a very good comparison.
It's rhetorical judo. You aren't supposed to like it.
You said understanding statistics (something outside of the person's will or effort) shouldn't impact him. I agree. Only you're not applying your own principle to gay marriage and the institution.
Now THAT'S an awful comparison. Why? Because you're comparing two people who love one another being allowed to marry to the impact of legalizing a physical assault within a marriage. They aren't remotely alike.If wife-beating were legalized (as same-sex marriage has been), it would greatly impact marriage, as an institution.
