He's selling coral and your selling coral. There is a fine line there.
Just because a guy has the where withall to go out and start a business is no reason to get so angry. He took the leap and started a business. Last time I looked, it seems every local fish store and internet guy started out as a hobbyist just like you, selling frags and decided to try and make a go of it.
Tell me you wouldn't love to do your hobby full time.
I for one was never "insulted" by him. From what I saw he was removed randomly.
Lighten up.
