Almost anytime I see someone argue "you might think it's because of X, but it's really because of Y," the person speaking is selling a particular ideology. That ideology magnifies Y and minimizes X.
It would be perfectly fine to say "you might be aware of X, but you should also be aware of Y." But pieces like this don't do that. They seek to tell you you are wrong if you think X. It doesn't sit will with people who have personally experienced X.
