Strimackus - his reference isn't to gay sunbathers, but rather to gay people who engage in copulation in the bushes - a public act of indecency regardless of whether one is gay or not.
And yes, it does take place over at the islands.
With regards to everything else you mentioned, it isn't a matter of "keeping" areas to ourselves, rather it is about ensuring that those, especially those who enjoy birds in particular, act with a certain amount of respect not for ourselves but for the sake of the birds.
The one thing that concerns me the most is the question of how close is too close...with respect to "mammoth lenses" and their minimum distances, we talk about 10ft or more. I'm 6'0" tall, and to envision someone only 2 of my body lengths away from an owl with at least 1' of lens added is still, in my opinion, too close.
I understand the concept involving full frame shots, but with that being said, with cropping and every other option available to us in post processing, I don't see the need to get that close to a bird.
