In all honesty, I'd be a lot more tolerant of "fighting=UST" if the whole "fighting is how mangaka work in BL codes" thing hadn't been used to justify pairing up virtually every 2 manga males ever, and to justify all sorts of "enemies as lovers" ships(and no, I'm not referring to Zuko/Katara or Hakkai/Yaone, but some where there is something seriously wrong with the idea because of the how and whys of the fight...it's like how the enmity between Rachel and...uhm...Trent[?] in the Kim Harrison books is meant to be UST, but everything he's done to her makes my stomach churn at the idea. Except that actually is meant to be there-possibly as an eventual red herring before Rachel/Ivy, I don't know.) I'm much more inclined to believe f/f "subtext" in shounen. Not because I see it, but because the target audience is adolescent boys. Shoujo mangaka tend to cram BL codes into the manga-either both ways or onesided-but I've never seen it applied to two males in shounen where it makes the remotest sense.
