Is this really your barometer for discussion, that all grammatical phrases must first exist in Google search results for them to be considered valid self-expression? If so that's pretty out there.
There's a wonderful irony here in that this a discussion about a Megacorp validating people's identity and here you are telling someone that their words are not valid because they haven't been validated by some other Megacorp.
The phrase "culture war" itself wasn't in use in English before it was used in the title of a book in the early 90s [1]. There were no search engines then.
