I take it you 'progressive-minded' gentlemen have no problem with bigamy, right? After all, these are consenting adults.This is precisely Santorum's argument. And he's right. If you follow the privacy doctrine to its logical conclusion, this is where it leads.
You're in a public forum. You are free to publically showcase your sin. I am also free to make it clear that your lifestyle choices are sinful, destructive and disgust me.
And again, your movement's attempts to force your choices on me and my family and on my pocketbook are an offense.
