I agree there's no reason for take one person's word for anything, but as for understanding Trump:

1)  We can look at who won the election.

2)  We can look at the poll #'s since the election, and see that the public is increasingly warming to Trump

3)  The marches decrying Trump as doppelganger Hitler have all stopped long ago.

Now, on point #3, if these marchers and fellow travelers online who say Trump is Hitler have given up so soon,  then maybe it's time for them to look at the true depth and sincerity of their avowed beliefs.
