Sounds awesome! Being in the Midwest, we don't have a lot of well-known hybridizers... I'm not in a position to travel much, so I miss out on Daylily Mecca and big shows... I just joined our state club this year, so I'm pretty new.
I'm shocked that someone would get his knickers in a twist because a seedling wasn't going to be registered... And to destroy it?! Tsk! I don't think I'd care if a seeding was going to be registered- like you, if it suited my hybridizing plans, I'd be thrilled to have it...
Too bad the guy didn't have a sunnier attitude... What a bummer...
