I'm not sure I understand the question. Why should people be included based on ideology? Put plainly, we want people who are factually right. Who wants otherwise?
The Middle Ages were defined, in a sense, by the priority of ideology over rationality. The enlightenment was a rejection of ideology in favor of factual accuracy about the world. The ideology may say the Sun revolves around the Earth, but the facts say otherwise. The ideology may say that that climate change isn't happening, but the facts say otherwise.
I'm not saying people should be excluded based on ideology, I'm asking what you do if a particular ideology is incompatible with seeking and holding "theories that withstand scrutiny".
Tbh, I think that is ultimately what we are dealing with - a very popular culture and ideology that eschews reason in favour of conformity.
