I hope the series goes more into how the 7th Calvery came to adopt Rorschach as part of their ideology and imagary. Rorshach was many things, allot of them dubious but he didn't strike as an ardent racist though he did rantg against immigrants. He was pretty damn complicated.
Rorschach was a sexist with some misogynistic leanings who murdered rapists. He was a Truman and nuclear bomb fanboy who refused to accept the death of millions in a scene reminiscent of a nuclear bomb that was supposedly for "the greater good." The intro to Watchmen - "The accumulated filth of all their sex and murder will foam up about their waists and all the whores and politicians will look up and shout 'Save us!' and I'll look down and whisper 'No'" is contradicted by the ending, where he does try to save them and refuses to accept their deaths as necessary. Arguably, that could make him the most heroic character in the original, but that's a long debate.
Trying to reduce him to a binary doesn't hold up. Several times in the series, the things he says don't match the actions he takes. If Rorschach were somehow put into this era, I don't think he'd be neither with the cops or the Seventh Cavalry, likely opposed to the Seventh Cavalry not necessarily because he disagreed fully with them, but because they murdered a bunch of cops.
Rorshach is a complex chasraacter. But the motivations of the Seventh Cavalry aren't yet apparent. They are definitely wearing white supremacist iconography but we've only been told they are racist white supremacists, we've been shown very little aside from their extreme dedication to whatever their ends are, willing to kill themselves rather than be captured.
Like things such as the so called "cancer bomb" which was speculation by the police, we really don't know why they were trying to acquire a bunch of Dr. Manhattan derived power cells yert It'll be interesting to see where it goes. They could definitely be simple bad guys or they could be after something more complex (maybe pawns in something bigger's game).
