I disagree. Agreeing on term definitions beforehand would solve all of these problems: The definition of religion is not “something that answers theological questions,” therefore the By Definition argument is ineffective for proving that atheism is a religion. (Incidentally, if that were the definition of religion, then atheism would be a religion.) For Hinduism, if someone tried to tell me that it was not a religion, I would necessarily use the definition of religion to prove them wrong. If Hinduism did not fit the definition of religion, it would not be a religion.
