Yes, it happened to me earlier this year. I was with a new group of friends (more like acquaintances) and we were hanging around, enjoying our drinks, and just talking about random stuff. One of the guys started talking about how he saw a 'woman' the other night, and he started making fun of how she looked. She was obviously a trans woman by the way he described her. Some of the other guys joined in laughter, but sadly nobody spoke up in defense of her, including me. If they only knew that a trans woman was in their midst at that very moment, maybe they would have thought differently. But then again, maybe not. Anyway I'm sorry, but I'm not going to out myself on behalf of someone I don't even know, in front of people I barely know. At least I didn't say anything to criticize trans people either. I just kept my mouth shut. Unfortunately this incident made me realize just how transphobic people can be when they are behind closed doors and when they feel free to speak their mind.
