Spreading hatred for groups of people via labels and encouraging their treatment as sub-human is popular rhetoric among nationalist extremists and political conspiracy theorists, but to satisfy the final condition (to be subjected in practice to a significant amount of suppression based on deceitful rhetoric), I think an easy argument could be made to put immigrants in that category, and maybe also homosexuals/trans people. You have to be mindful of that last condition though, since if you dropped it, nearly any group of people, sadly, would qualify as being subjected to such behavior.
