Yeah it certainly takes a while to reduce the stigma in situations like this. This subject is so heavily and systematically stigmatized.

The Robertson Panel determined our government agencies should gaslight us on the subject to avoid mass hysteria that the Soviets could exploit to cause panic (think along the lines of The War of the Worlds radio broadcast panic).

It'll take years to make progress reducing the stigma, but scientists and both commercial and military pilots around the world are beginning to facilitate that shift by providing their testimonies.

Edit: nice username by the way.
