Try to separate your opinion of Donald Trump from his family, and state what you think about them as individuals.
Are they independent thinkers or do they simply do as they are told?
Do they reflect the same\similar dirty politics as Trump?
As Adults, can they see Trump for who he really is, and know he's not going to change at age 70, thus neither challenge him on BS, nor support the BS. In otherwords, he is "Crazy Dad" who they love\support, but they draw the line on important private\personal issues because they know he will run over them if they don't push back on the important stuff.
I think his daughter is the brightest bulb of the bunch. She seems to be the only one who has any control or understanding of him and how mentally ill he is. The sons & son in law are just Trumpy lites. No more morals or values than he has. Ivanka knows where the money comes from and does what she has to do to keep it.
All in all - a sick bunch of puppies the country and world would be better off without. Unfortunately one can say the same thing about most wealthy and powerful people.
