Good luck getting out of there alive.
Not sure what your point is regarding Black clerics and the community, but I expect that he will get listened to respectfully and maybe there will be so murmurs in the background with a few individuals speaking their minds, but really this sounds like a bit of a streo-type (Assuming extreme sarcasm on your part) that somehow despite the extreme lack of popularity for Trump with African-Americans that somehow that just because he is speaking to a heavily Black audience that there will be any physical issues regarding the Republican candidate.
I could potentially see some potential Anti-Trump protests in Detroit, but still not sure where the hell you are going with this.... Confused???
