Ton of source material. OP can't argue on no basis. Maybe false basis but not no basis. I haven't look at the source material for more than 30 seconds - so I can't be any judge of it.
"Ton of source material...but I haven't looked at any of it for more than 30 seconds so I can't be any judge of it,"
Isn't that like saying, "There may or may not have been an earthquake. Tons of seismometers around, but I haven't looked at the readings so I can't say."?
'Volume' is not a useful metric... Tons of newspaper clippings on a schizophrenic's bedroom wall do not prove a conspiracy...
Thus my point you need to claim false basis if you have reviewed the source material and determined it is false. You can't claim no basis if you are just going to ignore what the other side is presenting.
