Joe, you are correct that Trump has never said "I accuse regular Democrat voting citizens of hating America."
But he doesn't have to.
He employs rhetoric, guilt-by-association, and
logical fallacy techniques to push the
theme that Democrats hate America, without actually saying it in those words -- which gives him and his supporters a measure of insulation from the awful and divisive ideas that he promotes.
For example, on 9/3/2019, Trump re-tweeted the following quote from
Lou Dobbs:"...Inexplicably and without foundation, they choose to hate America. The Democrats have truly become the party of hate."
But since Trump didn't actually say it himself, he can distance himself from the sentiment. (But why retweet it if he didn't agree with it?)
There's also
this tweet from 7/15/2019 where Trump says that the Democrats are "...endorsing Socialism, hate of Israel and the USA!" He's not making a distinction between Democrat members of Congress or 'regular Democrat voting citizens'. But the quote is vague enough that he can claim plausible deniability when pressed on the issue.
Another example is in
this speech from his rally in Dallas on 10/17/2019:
"The radical Democrats want to destroy America, as we know it. They want to indoctrinate our children and teach them that America is a sinful wicked nation. You see that happening all the time and I know it from personal experience what they want to teach your kids, not good. They come home, mommy, daddy, this is what I learned, and you're going, oh no, don't tell me. Let's get them into another school fast. They want to disarm law-abiding citizens, they want to take your guns away [Audience shouts "Boo"] and they want to win so far left judges to shred our Constitution. It's not happening. They want to tear down symbols of faith and drive Christians and religious believers from the public square. They want to silence your voices on social media and they want the government to censor, muzzle and shut down conservative voices. You know that. If they didn't hate our country, they wouldn't be doing this to our country."
Once again, Trump and his supporters can claim plausible deniability by saying that he was ONLY referring to Democrats in Congress, and that he was ONLY referring to the subset of those Democrats in Congress who are radical, and that he was ONLY referring to the still smaller subset of those radical Democrats in Congress who happen to also want to indoctrinate children and disarm citizens.
But do you think that the audience interpreted his quote in that way, or do you think his audience believes that Trump was referring to Democrats in a broader sense?
When Trump says "If they didn't hate our country, they wouldn't be doing this", the word "this" refers to, in part, supporting elements of gun control and separation of church & state -- issues which happen to be supported by the majority of regular Democrat voting citizens. So how is someone like @Jackstraw supposed to feel if
he also supports those elements of gun control and separation of church & state? Is it not unreasonable to conclude that Trump also thinks that people like Jackstraw hate America, or that Trump wants his audience to think so?
