Explain Baggini’s argument that homosexuality is not immoral.

in “Philosophy v Science”, Lawrence Krauss claims that science can “resolve even moral questions” (10). In support of that claim, he says that science tells us that homosexuality is not immoral because some people are naturally disposed to homosexual behaviorsEven though Julian Baggini agrees that homosexuality is not immoral, he claims that science’s discovery that there is a natural disposition to homosexuality does not show this. To show this, Baggini uses the example of rape. Explain Baggini’s argument (which occurs between line 63 on page 10 and line 11 on page 13); that is, explain how he argues (using the example of rape) for the conclusion that science’s discoveries about natural dispositions do not determine which actions are moral or immoral.
