i mean Jesus, the word is 'record' we don't call toaster ovens 'metal' or 'metals' that's the material it's made of.
If we're really going to have this conversation:
"Record" is like "album" in that it can be used to broadly describe a set of songs that are sequenced together. "Vinyl" can be and is used to distinguish a record from CDs, cassettes, and other formats.
It really isn't that big of a deal. People are mocked for saying "vinyls" because it's grammatically incorrect. If we're going to start ostracizing people for saying "vinyl" just because it's something that a bunch of people decide isn't cool, then I don't even know. I've been collecting vinyl since I was 13, and I've never had a problem with saying it.
