Ah, okies; the statement was unfinished so I had no idea what you were hoping/expecting me to do.
Personally, I don't think that one's belief in homosexuality being a sin has anything to do with one being homophobic. There are lots of folks I know who believe that "homosexual acts" are a sin but believe in full equality under the law; they're able to separate out their religious and civic/legal beliefs and recognize that not everyone may ascribe to their religious point of view.
Homophobia, by definition, is
...an extreme and irrational aversion to homosexuality and homosexual people.
...a term used to refer to a range of negative attitudes and feelings towards lesbian, gay, bisexual, queer, and in some cases transgender and intersex people. Definitions refer variably to antipathy, contempt, prejudice, aversion, and irrational fear
...the hatred or fear of homosexuals
...the irrational fear and hatred of homosexuals and homosexual behavior. It may also indicate a fear of being gay
...literally an uncontrollable fear of homosexuals and of homosexuality, but the term is generally used for a negative and contemptuous attitude to same-sex sexual relationships and to those who participate in them
...hatred, fear, discomfort or violence towards gay, lesbian, bisexual, intersex, transexual or transgender people.
Well, you get the idea. :)
Now, just because one believes something to be a sin doesn't mean that one is expression fear, hatred, aversion, discomfort, violence, or negative attitudes and/or thoughts toward it. Case in point, your discovery that a large portion of pro-choice women would not, themselves, have an abortion, due to personal/religious beliefs.
This is, quite simply, a case of, "I may not agree with that you have to say or what you are doing but I will defend to the death your right to say and do as you wish."
It's what living in a free, democratic republic is all about.
Is that enough of a comment for you? ;p
