Unfortunately, there are always going to be those segments of society who will never accept transgender people (or black, or gay, or...) There isn't much that can be done to change the minds of those who are bigoted, ignorant and self-righteous unless they choose to open their minds (and hearts). All we can do is keep trying to educate those who we can influence and hope the positive message spreads to the rest of the world.
I believe one major hurdle we need to overcome in educating other people is helping them understand the distinction between sex and gender, and therefore creating a better understanding of why we are transgender.
The term "homosexual" refers to a sexual preference or sexual orientation,and therefore has that innate relationship with sexual activity...that is why sexually derogatory terms were/are used, like deviant, pervert, etc. when bigots and prejudicial people refer to homosexual people. That is also why the term "gay"came to represent what it does...it is a word that can refer to a homosexual person or homosexual lifestyle, thus removing the direct attribution to sex.
The terms "transsexual"or "transgender" have nothing to do with sexual preference or sexual orientation...yet because the those terms are similar to "homosexual" and we are often categorized with the LBG(T) movement, many people fail to realize that distinction. In their minds, if you are transgender, you are automatically homosexual, and it is all about sex.
Not to mention people also still equate gender with sex, and when we start messing with that binary status quo, people get all kinds of confused about it. I don't want to diminish or criticize those transgender people that are well-known and public, but who are many of those famous transgender individuals? Models, maybe actresses (or adult film stars)...people who are objectified and sexualized by the nature of their status. When another transgender individual can't or doesn't live up to that "sexual" standard, they are again relegated to a lower status.
Other than trying to say the word "sex" as many times as I can in this post, I am saying that until people can see transgender people as people with a gender issue and not perverts with a sex issue, we will not gain the true acceptance and understanding that we need.
