There may be things "wrong with protectionist trade policies," but I'd hardly call them evil or immoral.
"Questioning our commitment to NATO," ... actually, he questioned other NATO members' commitment to NATO, and said if they don't step up, we may reduce our commitment to their level of commitment. Right are wrong, that is hardly an evil or immoral thing to do in peace time.
"[T]raditional Republican platform," ... who cares about that? Certainly not Trump. Certainly not you. Either way, setting that aside is not evil or immoral, or HIllary would be the most evil person in the election.
"And I think you should read the transcript of his speech last night before you make the SS comment." I will. I admit I didn't get to listen to it. Did he say he would go house to house?
I remember in the 90's the Clinton administration raiding construction sites, gathering up illegal aliens and taking them to the border. Companies had to certify that their workers were not illegal aliens, or they faced fines. I remember having to certify that I was a citizen when I applied for jobs. Enforce that rule, and provide entitlements only to citizens, and the situation will solve itself. No round up is needed. They will round themselves up.
