All of us "define ourselves" with our actions and our words.  The more "public" an individual, the more that definition is readily available for others. Mr. Trump's own actions over the years have defined him, and it's not a very attractive definition.  His tax records may be "pretty private", but his business dealings, his bankruptcies which have benefited him (his own claim) but destroyed the finances of others, his deplorable treatment of women in his personal life, and his huge collection of racist, xenophobic, homophobic, misogynistic statements and actions have defined him in a very public way.  

You continue to blame the "media" for the very low opinion the public has of Mr. Trump. Do you blame the media for the two wholly conflicting presentations he just made regarding immigration?  Those are actual videos of his statements, not "media" interpretations of what he said.  Mr. Trump is a "self-made" disaster as a Presidential candidate. Don't blame the media.
