Ooh... I think I'll do a complete translation of that sometime tomorrow. It'll certainly be useful for anyone who can't (or won't) read the manga.

Spoiler for still manga:

That war was over before it even began

There seems to be some people, even among the military, who are just fine the way they are, and don't want anything to do with men.

But the two ideologies are polar opposites. One side wants the Arume to return to two genders and let human society revert back to the way it was prior to the war, and the other prefers the status quo and would just as soon never see another man again. They can't possibly coexist, as evidenced in the example you stated.
The weird part is that the whole reason they came to earth was because of the former, but the latter seems to be the group in charge as well as the majority. It seems like something happened during or shortly after the war... like a coup or something.

I know there's sort of a reason for all the explicit content, but some times it's just too much you know. It kinda grosses me out.

Definitely. In most instances, the exact same things could be conveyed with different camera angles that aren't quite as gratuitous.
Maybe the mangaka is also trying to emphasize the oversexed behavior that's permeating the Arume by portraying it as shocking as it really is? I mean, they're on the verge of FUBAR'ing an entire race simply because they can't keep their pants on.

I whouldn't say anti-homosexual per se, but it clearly sets homosexuality as something abnormal. That could be taken as anti-homosexual though .

Also detrimental to society, apparently.
At least the effects portrayed in the manga aren't improbable considering the causes and circumstances.
