but we can take from it that there is something wrong when a member of one gender tries to mimic or appropriate the sexual values of the other.
Why because it makes most uncomfortable with it? it almost appears that you are looking for a reason to call it a sin! there are lots of references in the bible that we do not follow to the letter and are contradictions, so is it ok to pick verses and tailor the interpretation to suit what makes one comfortable?
There is no question that when the first women started wearing pants, they were considered crossdressers, but now you feel it is acceptable. why? because it has become a standard and common practice? I see Catholic School girls schools that include ties as part of their uniform!
“Matthew 5:29 If your right eye causes you to sin, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell.” I don’t see any one interpreting this in its literal sense!
I have consulted two priests and they said it was not a sin! There is much that we do not understand about this and so need to reserve judgment.
Some of the reasons indicated above as to why people crossdress clearly shows their ignorance on the matter and perhaps portraying their own mind set as to why they would do it if they had to.
I have seen lots of Crossdressers that are excellent people, husbands and fathers. They have used their feminine part of their persona to make their family and home an excellent nurturing environment.
No question there are others that have perhaps used it inappropriately, however there are many many heterosexuals - non crossdressers (most crossdressers are heterosexual) that are promiscus that does not mean that being a hetrosexual is sinful.
By the way it is a widely accepted fact that everyone has a male and female gender (not physical sex) component as part of their being to different degrees, some more skewed than others which can impact behavior, this does not make one persons behavior better than another, just makes us all different.
If this is the way God made crossdressers and that is the best way they can live a fulfilled authentic life, I do not believe our Loving Father would hold it against them.
