To be blunt, you are a terrible hiring manager if your red flag is “they haven’t got an up-to-date opinion about the shitty-history language that I’m personally into”.
This just sounds like PHP Stockholm syndrome with extra steps.
I guess it depends on how it's communicated. If someone tells me he doesn't like PHP because of this and that reason, that's fine. Getting wound up about some specific programming language (feature) or any tech still raises a red flag for me. But then I might be terrible as well :)
