I'm ashamed of this, but I also hate Kankers x Eds. Moreover, in the cartoon I like the moments with them, but not when in the fanart they have a romantic relationship.

No need to be ashamed! I admit to being biased towards Edd and Eddy pairings, which undeniably skews my perception. Additionally, I like to interpret Marie as lesbian, herself, so...a straight relationship obviously would be out of the equation. Eddy in the show feels so consistently intimidated and scared of Lee, pairing them up long-term, even as they get older, just doesn't feel right to me. May and Ed are kind of the only Kanker x Eds ship I've really warmed up to. Hell, I even find May and Edd kind of sweet as well. I think that has a lot to do with the impression that May's romantic feelings are the most legitimate (based on the direction the AKA team seemed to have taken with the limited stuff that is written about her).

Ultimately, these are all just my personal opinions : ) so even though Kanker/Ed parings are not for me, I do respect the art and work behind some of the stuff made out there. Everyone is entitled to their interpretations of the silly cartoon show, as long as they are respectful themselves. I do enjoy how people try to interpret the Eds interactions/relationship with the Kankers and vice versa as they get older. Even at an amicable level, I think that stuff is really interesting and wish there was more of it sometimes.
