What speeches of Trump, or "talks" of his, are you referring to?  You misperceive what was going on between those groups and the President-elect.  The groups you mention are well known to many of us: they have been studied for quite some time, for various reasons.  They are the groups that are some of the most discriminatory populations in the nation.  Trump communicated to them in a language he well knows from being around construction most of his life: stoking irrational fears, externalizing problems to "outsiders," painting catastrophic pictures of "our streets being over-run" with foreigners raping our women and stealing our money and goods; of taking jobs away from Americans; of letting in known terrorists and anarchists, and on and on and on.  It's all their in his recorded speeches and statements and tweets.  You missed it all, huh?  Or is it that you agree with it?  The answer is beginning to become clear, I think.
