You are correct. The whole “beware of protein” narrative is completely wrong-headed. People here would likely be astounded by how much protein strength athletes eat with nothing but positive health effects.
It's really more like a balance narrative. Hit reasonable ratios of protein, fats, and carbs.
High protein, low fat, low carb, low protein, high carb, high fat- collectively we've tried them all through one fad or another.
Currently IMO we're in a blowback period where we are seeing high carb is not panning out and many people are still afraid of fat, so protein is the next savior in line.
