An individual's attitude towards a sitting president is much more indicative of the individual than the president.
Presidents cannot be judged in the moment. Presidents are privy to a whirlwind of information that influence their every waking moment.
It is impossible to accurately judge a sitting president, especially through the prism of an agenda driven media (as all media is now)
So teaching your children to despise a sitting president or teaching your children to glorify a sitting president is dangerous and only indicates a lack of understanding of the lessons of history.
