That second sentence is perfect, thank you.
So weird that everyone was saying it doesn't exist... everyone believes that 'mob mentality' is a thing, there are plenty of examples of that being real. This at least seems related, like, acting like a mob even though you're not physically surrounded by people being all pitchforky.
Yes it's very obvious that the people saying it doesn't exist have an agenda and they are manipulating the data. By saying things like "not an academic term recognized in the field of psychology". Like yes, technically that's true, but they are obviously still lying and manipulating the issue. It's clear that they do not have an objective opinion, therefore their opinion is largely worthless and should be ignored.
