Disrespect?

When did it become acceptable, regardless of political affiliation to be disrespectful to a sitting President of the United States of America?

Am I the only one who notices this trend in all forms of media? Jokes and banter are one thing, and yes I'm all for free speech, however, what is up with all the openly disrespectful speech?

Regardless of your vote or affiliation the man IS the President, and deserving of respect. He has quite possibly the most difficult and stressful job in the entire world.

And he is the PRESIDENT for Christ's sake.
