There’s a lot of discussion about interpretation of the speech and reaction, but that doesn’t answer the specific questions, “Did Trump say this?” “Did the Scout Executive say that?”
My 15-year-old son says the speech reminded him of a “Bad Lip Reading” video. Some of those are hysterical.
The answer to both your questions is yes. Not saying that the executive spoke for all boy scouts. Some days half the posts I see is “fake news”.
