Ah, still telling yourself the same old 'people only think I'm dumb because they are partisans' thing.
The Trump campaign and associated people released tons of attacks on the Clintons, any number of which could have been the product of this meeting. It's not like information comes with a 'made in Russia' tag on it, haha. You have no idea as to the source of all sorts of information that came out during the campaign so if you're not basing this off of Trump Jr's statement you're basing it on nothing. That's even dumber, honestly.
Also, the fact that you think the Steele Dossier is 'laughable' is further evidence that you're allowing logical thinking to be overcome by your extreme partisanship. The most salacious parts haven't been verified but plenty of the rest of it has. Only an idiot would assume the rest of it is laughable at this point. A logical person would look at it as a document that we have confirmed has some validity but remains an open question in other parts.
