No. I’m definitely not having the ‘marginalised’ business! 
If a society has merchandise for members and one of the items is a tee-shirt or sweater with a logo on and it is not possible to have versions that fit taller people because manufacturers only make such items in sizes for average height people then that is marginalization.
I read a news item some time ago about how a girl who is tall ad larger was excluded from school for not having the correct type of skirt, which had pleats, because that style was not made in a size that was suitable for her, so her mother had got what she could get, namely a straight grey skirt, much the same colour. The article said where she lived so I wrote to draw the atrtention of her MP to the problem, with a copy to my MP, mentioning that to her MP. I got an instant automated reply from the girl's MPs computer system, but nothing further, though I did not expect to get any response due to parliamentary protocols and privacy - maybe the MP was already aware and maybe tackling the injustice - a letter to the Governors from an MP might well have an effect. I suggested that if a clothing supplier gets a franchise to supply a school uniform then the franchise should include a requirement that if a situation arises where they do not have the size needed then they must make a custom one and supply it at the same price. I did however get a very helpful and constructive reply about the general issue from an assistant to my MP on my MPs behalf.
I consider excluding the girl over that when it was not her fault is shocking.
