I’m so sorry. But you make very good points. You do have a right to make fully informed medical decisions, though I do not think it is a right guaranteed in the US constitution, unless you are counting life, liberty and the pursuit of happiness. But, in any case it is a cruel thing to do to a person in terms of medical history, genealogy, and also because it puts people at risk for unintnetional incest. I hope you find a support groups for LDAs. There are soe on Facebook. You can also find search angels there to help you find your truth.
