Criticizing a President

It is popular to criticize a sitting president. Perhaps it has always been this way. To me it seems a shameful thing to be critical of a president who is involved in wars to protect the country as well as many other countries. It is so easy to criticize and it is useful to point out ways to improve situations and make better decisions. But wholesale criticism seems to me to be childish or immature. It is much more difficult and much more constructive to suggest alternate ways of proceeding--concentrating on those rather than on criticizing, whose main motive would appear to be to somehow make one seem superior. To me such outright criticism always seems suspect and tends to disqualify the rest of the message.
