It is funny you ask because right now I have a lesbian couple over and they have felt sometimes that they need to point out that they are a couple to people before they show up at hosts. I could easily figure that out "inbetween the lines" when they wrote the first mail to me, and for me it was definitely not a problem. Why should it be?!
I find it quite sad that people still need to be afraid of going to places because of their sexual orientation. But ok, I have a lot of friends from very different backgrounds already. Maybe in some parts of the countryside there might be some more intolerance.
So, I guess I can be counted in on the "gay friendly" list - if it is enough that you care for how people are as persons rather than who they share their love life with. But we don't have rainbow flags all over the place or Eurovision-karaoke if this is what you mean. :P (Just kidding, people tend to have that idea about gay people and think all are the same.)
