Campsite said fully booked all year cause we`re gay!

I just got off the phone to a Naturist site in Dorset called St Anne's, and asked about space for camping in August and the first thing she asked was is this a Mr and Mrs booking, so I just no it will be myself and bf coming down. As soon I said that, "no sorry we fully booked then" I didn't know what to say so just asked about the whole year... sorry no fully booked all year. I thought this was odd so decided to ring back half hour later, this time inform her it will be myself and wife, this time however she replies with "can you ring me back in an hour I'm just down the field". ... I did and this time she started to arrange the booking stuff for the same sort of dates my bf and I cant go on cause there fully booked. At which point I confronted her about who I was and how an hour and half ago she told me they were fully booked all year, so started to go on about how they can have so many singles and couples staying. I informed her I was coming down with my partner and she just didn't want to know. Sorry but I find this sort of behaviour disgusting and not to the Naturism life style nor the human race. Please comment back if yourselves or other people you know have had this kind of treatment?
