Your example, then, proves your point: Persons here who post criticisms of the president or his policies are irrational?
And, presumably, all of the president's actions and policies are wise, rational, and to be applauded?
At least your remark did not seem particularly venemous. But I think it is silly and unhelpful to offer such a broad dismissal of those who criticize the president.
Oh no. I've criticized the President myself at various times. What concerns me are those wishing for a Democratic victory.
