Takes a good deal of courage I suppose to repeat and argument that has already been thoroughly debunked before you even made it.
What about "this day" is so "great"? Please tell me you don't seriously think it was when Trump read a prepared statement from a cue card, in the context of a 40-minute speech about how brilliant the economy had become, and in a speech that finished:
what’s happened to our country, and what you now see that’s been happening, is the greatest thing that can happen for race relations, for the African-American community, for the Asian-Americans, for the Hispanic American community, for women, for everything.
Because our country is so strong, and that’s what my plan is. We’re going to have the strongest economy in the world."
So, no. You've taken his words out of context by forgetting to listen to the whole speech and not just the snippet you want. Ironic, really.
