For the same reason I wouldn’t need to address the notion that “people go to school to learn organic chemistry” is not made “less false” by pointing out that people also, and mostly, go to school for other reasons. Never mind that most people don’t learn it at all. So yes, people teach hugs to prevent abuse. Whether it’s one, two, or all people, and whether other reasons exist, is neither here nor there when it comes to addressing the factual question that was asked.
does not mean that “a lack of studies would mean the experts are wrong” because that’s not how science works.
Just asking questions won’t identify misinformation that needed correcting.
