Quote:The Chambers Dictionary defines antitheism in three different ways: "doctrine antagonistic to theism; 'denial' of the existence of a God; opposition to God." To be clear, "opposition to God" is not in most meanings a statement that an antitheist believes in a deity but opposes the being in the manner of maltheism, but for various reasons the position that it would be bad or immoral for such a being to exist. All three match Hitchens' usage, not only a generally anti-religious belief and disbelief in a deity, but also opposition to a god's existence. The second is synonymous with strong atheism. The third and first, on the other hand, need not be atheistic at all.
