Hi Roberta,
Your concerns are valid. This year is an election year, so much of the political debate is about transgender rights and LGBTQ issues in general. In every city, some people are accepting and supportive, as well as those who are not. Our best defense during these times is camouflage. Act confident, and dress appropriately without extravagant outfits or makeup. We observe women who are just going about their day-to-day activities. See how they dress and behave and then do our best to mimic that. Most women are not targets, so we should appear like one of them and blend in.
While in the US Army, I lived in Germany for six and a half years. When I first arrived, I worried about similar issues of whether or not the locals liked Americans or not. Some do, some do not. I had not started my transition then, so my concern was only about how they felt about Americans in their country. I found that most people didn't notice, or didn't care. They have their own lives to attend to and I was just part of the background. Over time, I made many friends and even married a German woman.
My point is that we often worry about things that never happen. It is good to be aware of potential threats and think about possible situations you may encounter. I think that if you just relax and be your confident self, you will not have any problems. You might even make new friends!
