Is it really any wonder why Jesus ended up saying, "eat this"? lol...In the discussion of the status of birds in terms of food, there is no language of "clean" or "unclean" -- Lev 11 says that eating certain birds is not allowed because these birds are described as "sheketz" (despicable). The Torah provides a list of unacceptable birds by name. Because we don't know the exact translations of the forbidden birds, we have strong traditions dictating what birds may or may not be eaten. As there is no tradition that a dodo is acceptable, it would not be eaten, but the term "unclean" wouldn't really apply.
And someone who tries to proselytize in the anonymity of the internet and who dodges challenges and runs away from salient points would be a chicken. And therefore, edible.
