You mean that almost everything is political? That was my point.
I was wondering why we must celebrate those who only speak within their domain of expertise -- which is why so few scientists/engineers make their voices heard even when the science they create is being trampled on.

"Must celebrate" is too strong. But a good reason to recommend such people is that such people are easier for most listeners to recognize as reliable source of information in the domain. People who are vocal of their unrelated political opinions can be experts on the domain, but they are more polarizing and make people watch out or reject them.
