Considering that this person opposes ANOTHER set of rights-violating laws that are 'the law of the land' (same sex marriage bans and DOMA- so he only advocates 'the law of the land' on issues HE wants 'the law of the land' to be axiomatic)... well... I'm not ashamed to say that I went completely nuclear on this person. If he had said it in a different manner, I wouldn't have lost my cool... but the arm-flapping hypocrisy mixed with the "shut up, little boy" attitude was the limit. For good measure I hit him with the Fugitive Slave Act of 1850 ("so what would you have done if you had met a fleeing slave? Remember, it's THE LAW OF THE LAND!") before I cut off all communications with him. Ethics is something I think about frequently. Fuck, I've written essay after essay, I've had my works complimented by philosophers and ethicists alike. I'm not a fucking newcomer to this. Telling me to "Do everybody a favor and STFU" is the quickest way to Nuclear ville that you're going to get from me. And you'll have deserved every fucking moment of it.
I honestly have no desire whatsoever to continue to communicate with this person. I make some allowances for youth and experience, but when we're talking about someone who is old enough to know better, and someone who hits me with that attitude? Screw it.
