Did you mean "traditional charity that doesn't support ..."?

Apparently, yes. Editing.

First of all, the subject matter was charity in general, not your particular subset.

The reason I picked that subset was because I see a split between charities I would cluster as "problems the donor doesn't have" and charities I would cluster as "problems the donor has." If you (are likely to) have Parkinson's, then donating lots of money to Parkinson's research has direct benefits (see Brin). If you're never going to need your own anti-malaria net, then buying them for other people only has indirect benefits.

X-risk, as far as I can tell, should be in the "problems the donor has" cluster.
