> if a crank takes the theory of relativity to heart, does that invalidate it?
Absolutely not. Reread my comment. There are experts who describe the theory of relativity and link to papers supporting it. It is far better to link to articles from those experts than to articles from cranks who happen to get relativity correct but intersperse their articles with conspiracy theories.
A Flat Earther might write an article about geometry where the geometry is valid and then mix in unsubstantiated claims about the shape of the Earth. Would you say that is a good article about geometry? No. You would link to an article about geometry that sticks to just the facts.
