I don't have to like the science - it just needs to actually be relevant to the conversation (that is, people showering and using deodorant), and not a handful of essentially random studies dug up as flailing, ad-hoc support to a thread-wide crusade against basic hygeine.
Edit: To be more clear, if I hadn't already noticed all of your other comments spammed around the thread, I probably wouldn't have downvoted the studies you posted. It was the specific impression of disingenuously throwing any science you could at the wall and hoping it stuck that made me want to downvote.
Same reason I downvote most studies posted by vegans and creationists, actually - the distasteful practice of taking an ideological position and then trying to find/manufacture "science" to support it after the fact.
