there really was no coming back from your devastating argument that he had no business commenting on any of these issues. I mean, you know, props to the guy for bravely struggling on, but we all know you closed the debate then and there.
I have to say, though, it's really touching how much effort you're putting into trying to educate him in spite of that, despite him being such a horrible person who doesn't have the common decency to kindly excuse himself from any further discussion, because clearly he just doesn't have any respect for people with actual problems. Anyone can see that only you, with your profound understanding and empathy for the people in question, are showing such respect.
