Why should I not see transsexuals as being deceptive?

I have no problem with the transsexual community; to each his/her own. However, I am very judgmental on how people portray themselves. I do not believe I have any right to tell others how to act or look; however, I see those who are genuine with me with the utmost respect. When encountering transsexuals, I see those who intentionally portray themselves as not who they are as being deceptive, which I disrespect. You feel some way, that's fine. However, do not portray yourself to me in such a way to show how you "feel" as opposed to who you are. Are there other ways I should see this?
