"I'm waiting for "Gay Days" at this festival"
I doubt you'll find "Christian Days" there, either. I went to the site and checked out the photos and some of the novelty items they sell there. It's borderline porn.
What I am trying to say is this: Did the website have the right to publish the gay week and let people know? Yes, they did. Do straights have the right to know what is going on in the way of special events such as a gay week that they feel might expose their children to a life style they don't necessarily agree with ? IMO yes, they do.
This is all the article is about, not if you like gays, don't like them, but about freedom of speech and choice.
