in this case you bashed a religion unprovoked
I'm a christian and I wouldn't ban someone on my server for making a joke about Jesus. Getting butthurt about someone poking fun at your religion serves no purpose as to grow your religion, it only further polarizes the religion itself from the non believers. Using power/authority to censor people's speech to keep them from offending anyone is never a good idea, and in this case it seems that the Mod himself was the one offended, making this not only an attempt at censorship, but also a means of getting personal revenge.
Does this mean that I think it is ok to bash people's beliefs? No, not at all. I just think it is wrong to use the power of an institution to control what people say.
