I think that what @BodyBySisyphus@hexbear.net said above is actually what's going on here, and this bigboig clown doesn't understand that the meme phrase "least x y" is always meant sarcastically. They really are saying "wow look, a hexbear that doesn't argue about everything." They're still a dumbass and they're still thinking they're cleverly dunking on hexbear, but they are not saying "this user is extremely contrarian even for a hexbear." They don't understand the idiom they're using.

It just doesn't make any sense otherwise.
