I respect Kerdly just as much as I respect Krusie, Kriselle, Kruselle(?), Suselle, Kralsei etc...
I respect any ships as long as it's a consensual relationship between characters that are either all adults or around the same age and that doesn't involve related individuals.
I don't like ships around unbalanced dynamics/abusive relationships if it's not there to make a point (e.g. bakudeku (far fetched I know), one told the other to jump off a building and the other just stayed friends with them without getting an apology. Not a fan).
On one hand, I think Kerdly is a nice ship. It takes Berdly's character and fleshes him out, making him more than the 'annoying pretentious smart boy character', just like in the game! But more! Oh and also there's Kris and it's cool to see two loser nerd teens together.
On the other hand, I think it's hilarious if we see it through the 'Berdly IS just the annoying pretentious smart boy character and it just happen to be our second save', though it's more a crackship than anything.
