Not at all. It's a magazine by fans for fans and represents different viewpoints. All can be covered in this excellent publication and the more diverse the perspectives the better.
Question: if the request was for a disabled fan to write about issues specifically affecting disabled fans at football or their match day experience would this request also be "very odd"?
I don't equate being part of the LGBTQ community with being disabled.
I'm also not particularly interested in reading about the day to day life of fans, whatever way they express their sexuality. I don't find it odd that if they wanted to write an article about an LGBTQ person that they would seek out an LGBTQ person. I find it odd that anyone would be interested in this sort of thing.
I suppose if it helps an LGBTQ person feel more comfortable or if it dispels some myths about football being full of homophobes (it is), then all power to them.
It's not for me.
