This is the United States. We have rights, and that includes the right to offend people and be offended. Without this diversity of opinions, the whole character of the US would be lost. Until offensive statements are backed up by actions, they should not be illegal, although they may be rude and inappropriate.
One of the defining qualities of the United States is our freedom of religion. We have the freedom to practice any religion we want, and we have the freedom not to practice another's religion or any religion at all. Likewise, we are free to express our opinions about others' religious practices, positive or negative. It may be rude to criticize, but it should never be illegal.

Just to make an offensive statement should not be a crime. I do think that some people are ultra sensitive to religion and often use it as a crutch. However, it should absolutely be a crime if someone makes a threat or uses profanity against a certain religion. Religion is always a touchy thing.
