I think it's relative thing to categorize people as real bitcoiners, I mean if someone acknowledges bitcoin advantages but chooses to just hodl in an exchange not a real bitcoiner? It is in my book, sure he does not hold the keys in fact he just has some IOU but it's still demand for bitcoin, it's probably someone who would accept bitcoin payments. I think maxis get a "toxic" label from other mostly because we are bitcoin only, and saying to some noob that is into crypto that everything else except bitcoin is a scam without him understanding why that is might come off as extrimist "toxic" person.
