Patriotism means to stand by the country. It does not mean to stand by the president or any other public official, save exactly to the degree in which he himself stands by the country. It is patriotic to support him insofar as he efficiently serves the country. It is unpatriotic not to oppose him to the exact extent that by inefficiency or otherwise he fails in his duty to stand by the country. In either event, it is unpatriotic not to tell the truth, whether about the president or anyone else.
The logic now in use serves rather to fix and give stability to the errors which have their foundation in commonly received notions than to help the search for truth. So it does more harm than good.
A man who lies to himself, and believes his own lies becomes unable to recognize truth, either in himself or in anyone else, and he ends up losing respect for himself and for others. When he has no respect for anyone, he can no longer love, and, in order to divert himself, having no love in him, he yields to his impulses, indulges in the lowest forms of pleasure, and behaves in the end like an animal. And it all comes from lying - lying to others and to yourself.
