Unironically, its more likely to me that the trend doesnt exist. Its very easy to attribute to people a position that they don't have, and then others see that people saying such and such trend exists without bothering to fact check. As a general rule, people want their positions to be understood. If someone supports a position, theyre going to own up to it more often than not.
Also, the biggest mistake people have been pointing out is not sticking to their guns and training Anakin as a Jedi. Their first impressions about him were exactly correct.
