Lots of LBGT doesn't mean tolerant or non-judgemental. In fact, sometimes familiarity breeds contempt, for a few reasons.
First, a lone T person is perhaps odd to some, but not threatening. Look at areas that have the most anti-immigrant sentiment. Hint: They aren't areas without any immigrants! People start acting out towards immigrants often because they feel the immigrants are "taking over." One immigrant wouldn't do that. Similarly, one T person in a town probably won't cause too much of a fuss. But if the right wing thinks T people are taking over, watch out.
Second, people who have never come into contact (knowingly) with a person who belongs to a minority will generally not think they understand the minority. Some of the most horrible stereotypes and such I've seen towards minorities comes from people that know a handful of people in whatever community and, thus, *KNOW* what "those" people are like. This is particularly bad with law enforcement - they come into contact with T people predominantly when crime is being committed. They don't ever come into contact with T people who are not committing crime. Thus, they start to think all T people are committing whatever type of crime - after all, they have a lot of experience (so they think) with T people.
Third, even in liberal areas, there are crazies who think they are being persecuted by the liberals and need to fix it. Harvey Milk's killer comes to mind. As do the disproportionate number of T people who are murdered in supposedly friendly/liberal communities.
Forth, if an LGBT law is getting passed, watch out. Hate crime went up in California when gay marriage was initially allowed. It'll probably go up again, since "Kindergarteners are going to be told that they can have a sex change" (that's basically what Focus on the Family and others are saying in California right now - it's calculated to cause the most fear and most likelihood of getting the conservative values-vote to the polls). If my children are at risk, why wouldn't I want to attack the person putting them at risk? Likewise, DC saw too many hate crime murders recently, as did Houston. DC is constantly in the news for allowing same sex marriage. Houston has a lesbian mayor and just confirmed a wonderful female municipal judge that the bigots think is a man. In places like that, the bigots feel like they are losing. And crazy bigots who think that they are losing and that their children are at risk are just plain dangerous. It's basically the same recipe world-wide for terrorism - crazy bigots who think they need to do something to stop the moral decline. Even when it's not a terrorism, but a seemingly isolated nut that isn't trying to send a message, a lot of campaign garbage about how horrible gay and trans people are is likely to give support, in the bigot's mind, to violence.
So...I'm not sure if one place is more or less trans-friendly than another. I'd stick with some place that you can feel comfortable in, that you understand, and that you feel as safe as you can feel in.
