Redditors arguing against about someone not having standards is the pot calling the kettle Nigger. Their argument boils down to Rorschach having conflicts in his morality (some of which are ridiculous, there's a difference between nuking an enemy country in a war, and killing random people hoping for a chain of events that might create a temporary break in the cold war). But everyone have their contradictions, and considering Rorschach lives a hard life and dies for his beliefs, the contradictions only humanize him further and he still ends up having more principles than any other character in the comic.
Predditors love flipping between death of the author and media literacy to win arguments. And, no shit, Commie Snake God worshipper Moore tried writing Rorschach as the most vile Objectivist hero he could envision, but in a classic case of "evil cannot comprehend good" sane people still love Rorschach despite his faults because he acts in an admirable way.
tl;dr I fucking hate Redditors.
