The kitchen joke was not really that bad, its so overused it self-implies that its a joke. But saying "Your loving disabled." That is simply forgeted up. By that logic I'm sure you laugh at car accident and disaster victims as well. You are an starfish.
But before you try the "Oh i made one joke and im an starfish" stuff, no, that isn't the only reason. The reason is that you even made a topic asking whether you went to far and insulted the people that said you did. You are being ignorant to the fact you did something wrong and saying "I'm not apologizing" just further proves my point.
Grow up douchebag.
