No. Words have meaning. "Are you under the impression that he's the only USSC nominee to have never gotten a hearing?" Means exactly what it implies: he wasn't the only one.
If I'd have ntended to say it was common I would have said so.
So you really believe the fact that three other justice nominees in the 19th century not getting a hearing was relevant to the discussion you were having about Merrick?
Okay....I guess.
