I'm not them though, so I'm not certain.
If you had tried a bit harder, I think you could probably have determined what answers they intended for the questions you asked.
Well, not whether they used specific sites, because that was probably irrelevant to what you wanted to know/the point you were making.
But for the actual point of your question, you could have probably determined how they intended what they said to correspond to your questions.
I mean, obviously it's difficult to do that when talking to someone one disagrees with (sometimes it will take me a number of paragraphs of my response until I figure out a way to interpret what was said in a way that makes significantly more sense than the first interpretation I noticed). So, it's certainly understandable to not realize a more reasonable interpretation. But at the same time, it's I think generally better to look for one, to see if one can find one.
I just wanted him to say it himself to see if he can understand how flawed his justification is. Watching him weasel out is just for fun.
