Trump thinks he is the only one who can be politically incorrect. He is wealthy and earned the right to poke people in the eye.....Gellar did not earn that right through wealth or status, so she needs to be condemned.
Trump is an elitist of the worst order...an arrogant elitist who brags about buying politicians, defends his sexist comments and condemns “little people” like Gellar.
Most of that is his personality type, who are generally quite successful. Trump knows the game so he plays the cards ...one of which is and always has been politicians are for sale. You give to them they give back...nothing new at all about that, and the terrain he has had to contend with in business as most do at his level of work. "Little people" as you called Gellar...know this as well...most don't like it but it is 'the game' at every level of life in business and otherwise. Trump and others like hi simply play it in a higher level of revenue and power.....I've seen it in all places I've worked as I'm sure you have.
As for his sexist remarks....there was a time where woman and en did laugh at jesting over woman...now it's only the men who have to take it.
