It's never perfectly fine to just reject science. People do it but that doesn't make it acceptable. It's got nothing to do with identities but to do with what is supported by evidence, what someone is justified in believing. You can't try side-step the issue by talking about other aspects of their lives. If someone is rational in everything except believing that chocolate-chip cookies cure cancer that doesn't mean that disagreeing that chocolate-chip cookies cure cancer is policing his identity. It's a claim that he is not justified in making in the first place.
"If all mankind minus one, were of one opinion, and only one person were of the contrary opinion, mankind would be no more justified in silencing that one person, than he, if he had the power, would be justified in silencing mankind."
~John Stuart Mill~
