Ultimately, you're right if the only consideration is simply the administration of the site. There are other considerations. For example, is the Study what this site wants to be known for? Does the activity in the Study reflect positively or negatively on the rest of the site? Do the conversations in the Study positively or negatively impact the entire community?
It would be different if there were debate in the Study, but I disagree with you. There is very little actual debate occurring in the Study. What occurs in the study, on both sides, isn't debate. It's not even discussion. It's two parallel rants that seldom intersect. There's no exchange of ideas. It's about two things: who can yell loudest, and who can yell longest.
Hasn't always been that way, and it doesn't really need to be that way now. Suggesting that it's something that people should just ignore is like saying that there's a tumor growing on your arm, but just ignore it and use the other one. Like a cancer, it needs to be addressed. Whether that's to get it under control or to excise it completely is a matter to discuss. But, IMO, ignoring it is not an option.
