I seem some sense to the arguments for H'rothgar. But it's mostly along the lines of "they might have wolf heads" which isn't much of a reason to support them.
I don't hate the new race, just feel like a much better job could have been done.

Like no H'rothgar at all and instead maybe two new faces per existing race?

As for the human-like races point, I thought that was the entire concept between what separates us form the beast tribes. At least that seemed to be the case with many points made in the game.
Maybe a bit racist but it looks like all the human looking races joined up for that reason. Which as tied into some of the good politics in this game.
H'rothgar seem to go against this, I mean why would the Lupin be considered a beast tribe now? Because the powers that be said so? "These animal men are beasts, these animal men are not."
