well no my view is almost the exact opposite : it's "if no one else on the pitch is allowed to wear it, then the referee shouldn't wear it either "
You are making a moral assertion with neither law or actual data top validate it.
I have a fairly good female referee in my society. She likes to be well presented at the game while not drawing attention to herself. She sometimes wears stud earrings, and I have yet to hear a murmur from anyone about them. In all my years of refereeing - just over 20 - I have never had head or ear contact with a player. I don't think I'm unique. Can you tell me if it's OK for her to wear a hair band to keep her long hair in place? If you're being consistent, then the answer is no.
By your standard, I should be making sure that any Christian wearing a cross around his/her neck should have it removed. Whilst not a believer, I would oppose that kind of restriction wholeheartedly.
I have circulation issues with my hands in very cold weather. By your argument, I can't wear full gloves. That deprives the teams in my area of a referee, in an era where, in contrast to Hampshire, we are resource constrained.
I wear a CGM in my belly, and carry the receiver in an arm strap. I also carry my radio kit there. Is your serious argument that it's OK to carry the radio there and not the CGM? By the logic of your argument, that is what you are saying. But if the radio kit is on, that's the risk element present, not the CGM.
I'm trying to create a welcoming environment for referees. I don't think your stance is that.
Now, you're going to look at my list and say (for example) that the CGM is OK. If that's the case, then the debate is about where the line should be drawn, and the not the absolute nature of the line that you're proposing
