Why Do Someone Disrespectful?

Isn't it ironical, how someone can say “Make America Great again” when they can’t even follow the law or treat everybody equally regardless of their gender and not have the willingness to help others?
Yeah, as you all know or should know, from the debate of the presidential election and the CNN news report on the 13th of September, 2016, Donald Trump has not only been harassing women but also did not make a single donation since the last donation he made in 2009, which the amount that didn't exceed $10,000, to the police athletic league of NYC.

Other donations that were taken place during that time under Donald Trump's name was done by using money that belonged to other people and organizations who Donald Trump had connections with. David Fitzpatrick, a reporter from the CNN, has asked 326 charity organizations about Donald Trump's contribution for them and as expected he reports that out of 326 organizations only one of them were donated using Donald Trump's own money. This again shows how Donald Trump is an ungenerous person, and I think the qualifications for becoming the United States president, includes one being generous, equal, honest and respectful as well as being suitable to be an anchor for the citizens and the nation to rely on, and Donald Trump so far isn't doing so well in fitting into any of these
