A club only for those with natural red hair, only start ot if you yourself are a natural redhead. The rest of you, start up clubs for members who naturally posses some phenotypic trait you possess, start up a blonde haired league, a blue eyed league, a green eyed league, etc. Just leagues based around phenotypic traits most predominantly found in White peoples. No laws are against this, and you can point out that some non-White racial populations also naturally have these traits and would this be welcomed as members (for example, the naturally blonde haired and blue eyed Australasian people of Vanuatu, who are brown skinned). There just doesn't happen to be many of them in your area, but if there were, they'd be welcomed with eager and open arms. But there just happened not to be many in the region you live in, what a shame, still you can't fault your club or its organizers for this. They just wanted to be around others who share this one trait with themselves.
