Hi Jacob, welcome to our little corner of the web.
I hope you will be patient with us. Undoubtedly, you will find some persons who say things which you will not agree with. Perhaps you will even disagree quite strongly. Such is the nature of the internet, and Catholic Answers Forums (or CAF as we often call it) is no different. Hundreds of people post here every day, from all walks of life and from countries around the world. Most express themselves with charity (aka “love for our neighbor”) and avoid the temptation to insult or offend. However, from time to time you will encounter persons who are not expressing themselves with charity. Rather than respond to fire with fire, the thing to do is to report an uncharitable post to the forum moderator. The way to do that is to click on the little red triangle which is in the upper right hand corner of every post made here.
As you may have noticed, this discussion thread was started a year ago. I mention that because it is worth remembering that anything you post here will exist pretty much for as long as the internet exists. Years from now, Google will still turn up this discussion (or any other CAF discussion) and all of the comments will be readable. Please keep that in mind when deciding what you want to share with us.
Okay! Now that I have thoroughly bored you, I will respond to what you have written.
This is a Catholic forum, sponsored by a Catholic organization which explains and defends Catholic teaching. So a bias towards Catholic teaching will be unavoidable. The members of CAF tend to be strong supporters of orthodox Catholic positions. They also tend to be politically and culturally conservative. You will find some members here who do not fit those descriptions and they are welcome so long as they remain charitable in their discussion. But I think they need to exercise a lot of tolerance for opinions they disagree with and which they encounter regularly.
For example, you believe that crossdressing is not a sin. A Catholic would say, in light of Church teaching on sexuality, that it might be in some situations. Actors crossdress as part of their profession, and women often wear male clothing without eliciting concern. Surely such things are not sinful. Does a man wearing female clothing, in itself, constitute sin? Probably not, although it may distress onlookers who are uncomfortable with the idea. However, if someone crossdresses to achieve sexual arousal, the issue becomes complicated… more complicated than I will deal with right now.
Regarding that Bible verse which you objected to, don’t worry about it. It is no longer morally relevant but was part of an archaic legal code to set the Jews apart from their neighbors. Deuteronomy 22, and similar chapters of Deuteronomy, are purely of historical interest. Much of it sounds strange today, for example, saying that clothing made from two different fibers (say, cotton and polyester) is forbidden. Yet few Christians or Jews today would scruple about wearing a cotton/poly shirt. So don’t worry about Deut 22:5. If the Bible is truly against crossdressing, it will say so elsewhere.
