I remember that well, actually, which was why I was confused by your speaking as though you have been proven right about something. So confused that I dug up the conversation you’re referring to. Here is what I said, with emphasis added:
I understand what you’re saying, but if someone’s pouring water into the kitchen window of a burning house you don’t tell him to stop just because he might not save the master bedroom. I’m not going to attack anyone opposing the rape of Syria just because they might later be useless about Iran or Venezuela.
Opposing US military interventionism in any country is intrinsically good. The fact that they’re worthless on another country doesn’t make that any less true. If you think it does, all I can do is repeat what I told you last time: I don’t respect your perspective on this subject.
