There are a lot of 'ships I don't believe in, but there's only one I've ever had any actual begrudgement for: J/E. That's because the people in every other fandom I was ever in - even the batshit crazy X-Files 'shippers vs. NoRoMos - saw their 'ship as fun, whether it was canon or not. They didn't spend all their time trying to tear down what other people liked.
