> Because it is in fact the messaging which is the problem, not racism or sexism
Yes, of course, the reason Republican voters embrace the concept of deplorable is because the Dems are mean to them. That totally makes them noble and not in fact deplorable.
> It is the messaging of the Democrats that pushed so many people into Trump's arms
He got less than 50% of the vote, if the Dems are pushing so many people to Trump they are doing a crappy job of it.
Though I do agree that the Dems suck on messaging, it is not because they villainize Republican voters. It's because they don't focus their efforts on bread-and-button progressive priorities like labor and healthcare. They blew their wad on trans rights, which just isn't a great strategy to move a lot of voters to the polls.
