I saw that column in the paper too. At the time, my main thought was, what would happen to this guy if he said he had "Black fatigue". I bet he'd be fired. I understand he may not be a homophobe, but at the same time, there's just some things you should keep to yourself, especially selfish feelings such as his. It's his own damn fault he has "gay fatigue", since as you said he is welcome to change the channel.
I think anyone who is upset over the visibility of gays increasing isn't really on our side to begin with. My retort is we've spent our entire lives with 'straight fatigue', so get over it! ;-)
