Probably not. That would be equivalent to including someone who claims "radiation from computers interferes with your brain" on this AI panel, or perhaps someone who claims "krakens pose an immediate danger to inattentive sailors" on a maritime safety council.
Most people can tell the difference between someone you don't agree with for ideological reasons and someone you don't agree with because they ignore facts for attention. I'm assuming the poster was referring to the former. There's a big difference between say, having a Republican on the committee vs a Holocaust denier. While it requires a certain amount of empathy to realize that rational people can have the same inputs as you but produce different opinions, I think it's a beneficial thing to recognize.
The Heritage Foundation literally falsified studies to go after LGBT people and claim they are unfit to have children. This isn't just about being ignorant of the facts or having behavior that proves you to be unqualified. This is about being completely counterproductive to the goals of the committee. That is exactly like having a flat-Earther on a space exploration committee. Furthermore, this inane argument about intellectual diversity to have ignorant people on an expert panel applies just as well to flat-Earth believers as it does to the Heritage Foundation.
>...rational people can have the same inputs...
Not everyone is equally well informed and well intentioned.
