Earlier quoted context omitted.
They want the government to replaced by the free market for other people . For them, it's government benefits all the way. The political scientist and author Frank Wilhoit talked about it in his works: > Conservatism consists of exactly one proposition, to wit: there must be in-groups whom the law protects but does not bind, alongside out-groups whom the law binds but does not protect.
Errrhm, all the "protected classes" tend to come from the left wing ideologies. Sure, the right isn't what it used to be with Jeffersonian liberalism and free speech, but that quote could easily be interpreted to be about modern left by simply replacing "Conservatism" with "Liberalism'.
That doesn't seem to be what the quote is focused on though, where most efforts around "protected classes" come from. I think it does a rather good job highlighting it's point about conservative central hyperfocus on the supremacy of an in-group. Seems to be a pretty strong candidate for an underlying proposition at least, given some of the imagery we've seen over the past days.
