We like their friendship and Kurt is a pretty fun characther, they are true bros, so must of us don't mind the jokes. I personally never saw their relationship as something romantic, but shipping is not about what is canon or not, so enjoy it as much as you want. And hey, if they decide to make Logan bi (as Claremont apparently intended) Kurt is definetly the better choice (nothing againts Cyclops, but i take Nightcrawler over him any day, regarding that).
