I also saw that page going around, and it annoyed me a little, but we all have to realize that for the most part, when people are trying to decide whether you are male or female, they are just trying to be polite, because for all they know, if they guess wrong, you may possibly get very offended. In general, people are just honestly trying to do what you would want, and since you cannot always tell every random person on the street what you want, they're going to assume you want the pronouns of your birth gender.
