I would hope that every American on the list is a critic of the proposal. There is only one thing I can think of that is un-American, and that is a failure to question authority.
Are there any opponents of the proposal(s) on the list? I searched way back for quite a percentage of postings, expecting I might find DougR and pdq perhaps. But DougR repeatedly said he was just seeking information and opinions. pdq said "Yes, 100% of respondents should say that 'all people should have access to quality health care'. Pollsters ask silly questions quite often."
Unless and until someone says otherwise, I think the answer to that is pretty clear.
