Jim Harbaugh's call for '1st-class' conduct on social media draws comical reactions

From his 10-month-old Twitter account with 322,000 followers, University of Michigan head football coach Jim Harbaugh made a simple plea on Wednesday for civility on social media.
Here it is:
It's a good and wholesome sentiment. Of course, it's a vision that will never be universally realized. Twitter, Facebook, Instagram, etc., are infested to some degree with hatred and negativity toward student-athletes. Michigan punter Blake O'Neill learned that recently, perhaps part of the inspiration for Harbaugh's plea.
Anyhow, Harbaugh had to know he'd attract some blowback. Some folks pointed to alleged hypocrisy of the "1st-class" behavior appeal coming a guy famous for sideline histrionics. Also a lot of people responded with approval, but take a look below at some of the funnier, more controversial and sad-random responses:
@CoachJim4UM like the way you conduct yourself on the sideline, constantly berating officials who are just trying to do their jobs? Got it.

@CoachJim4UM Make sure you don't read @JedYork timeline then. Its very low brow but it's his only form of accountability.

@dmansworld474 @CoachJim4UM Didn't realize part of your job was to scold coaches over social media. Stay in your lane.

. @CoachJim4UM You're asking something that is impossible for a fan base (OSU) to accomplish. They can't resist from the temptation.
