First I have two friends that are Transgender, they are both wonderful human beings, and not freaks. You would do well to get out of your bubble and meet people who are not like you.
Second, that order is stupid, you can't legislate against science. All it is going to do is discriminate against these people. One of my friends already had lost her job when she came out the last time he was in office. Is that ok? Are you ok with someone losing their job because of who they are?
