You seem to have a bad attitude going into it. If you have thoughts and feeling and you can explain your position when 'under attack' then you need not be worried about such things. If you think people discredit your opinions because of your penis then you are wrong. I am not saying that discrediting your opinions is a good thing or valid way of discussing things but the reason for it is not your genitalia, it is because male, female, trans etc all have very different experiences of how society reacts/treats their gender or sexuality. Some people may get agitated when they hear someone who is not in their situation, talking about their situation. But that is because of their past experiences and if you provide a comprehensive explanation of your beliefs, then there is no reason for you to worry about how people react to you, because you will know you have been understood. Some people are quick to throw opinions around without reason and it means people like you become afraid to voice yours. If you focus on what you are trying to say then it will contribute to a discussion and if it descends into something you did not expect (a twitter witch hunt?) then you know that you have articulated yourself in such a precise and intricate manner and you know your remarks cannot be taken incorrectly.
