I could say that you have consumed leftists propaganda about Trump. But I won't.

For starters, stop thinking of people as masses. They are capable of making intelligent decisions.
I think I understand why when choosing between Clinton and Trump people picked Trump. This was logical decision for many of Trump voters.
It would be very helpful for the current US democratic party to understand why people voted from Trump without pinpointig it to racism and homophobia and other sins.
