Why not invite him back, via twitter, to spell out how Froome and Horner became unicorns?
This is why arguing with a few of the obsessives is so tiresome. As you no doubt know, Vaughters position on Froome (as opposed to Wiggins) is "I don't know". And his position on Horner, judging by his twitter feed is one of outright skepticism. And as you equally well know, his cleaner cycling argument includes an assumption that some people are still doping and that some winners are still doping. So he doesn't have to take the view that any particular rider is clean for his position to be consistent.
Yet despite knowing all of that, you still choose to misrepresent his views, attributing arguments to him that are, of course, easy to knock down. If you were actually interested in developing a useful discussion you would want to take on his argument in its strongest form.
It's not just you (although you are one of the main culprits) but the atmosphere in here is completely toxic. Not because there are loads of posters who think everyone is doping, or because there are loads who think that the sport is cleaner, and loads in between. But because so many people both make arguments here in bad faith and, consequently, assume bad faith on the part of everyone else.
