3. Make a good impression. Whenever you are in situations where you are able/willing to disclose information related to your trans status try to do it in the most friendly way possible. A new doctors office may be a good example..Or let's say you are with a family member who has brought along a friend of theirs that doesn't know and the person makes an insensitive comment regarding transsexuals or any GLBT member.
If you find yourself wanting to address it, do so in the most friendly manner possible. Sometimes when people realize they are face to face with a GLBT member after making such comments they end up in an "Oh Shit, I'm sorry!" mode. I have found that people in such a situation people either get really defensive or really apologetic and if they end up apologetic they are going to be more willing to hear what you have to say and actually take it to heart.
Coming at them in anger mode will have far less influence over their feelings in the long run then approaching them in a friendly manner. Influencing one persons opinion can/will often result in them becoming an ally willing to help extinguish the hateful views about GLBT members when and where they can. Of course with people who make really strong statements its probably not a good idea to address it even though you really just want to rip their head off. Verbal sparring won't make you feel any better and it's possible you end up more upset. It's not worth the time and energy with those kind of people. Save that energy for someone who is more willing and able to hear you out.
4. When making donations do your research. Sometimes without knowing it we end up financially supporting businesses and non profit organizations that are opposed to equal rights for GLBT members. Do what you can to keep your money working for us and not against us. Encouraging friends, family and allies to do the same thing is a great idea. I will add links for GLBT friendly companies, nonprofit organazations as well as a list of known Anti-GLBT organizations to the "Trans Related Links" page that will help us all be able to be a little more knowledgible when it comes to who we give our hard earned money to.
