Except no.  Your book purportedly states that committing homosexual acts is a sin.  It doesn't state that baking a cake that will be used as dessert as part of a meal celebrating the wedding of homosexuals is a sin. If one does not participate in physical acts with another of the same sex, he/she isn't actually doing anything against your book's code of rules.  So, you are in fact filled with imaginary fears and beliefs about your own book.
