The beginning of Oshi No Ko is a perfect representation of this. It's this point exactly, especially since VTubers can be heavily compared to idols yet remaining even more anonymous.
Yet a fair portion of that IRL fanbase are just focused on sexualizing Ruby, Kana, Akane, and Aqua to name a few (they're all underaged by the way) and having that obsessive interest over them to the point it's technically a parasocial relationship with the series.
This is all instead of actually seeing the main point: That the series is criticizing them and calling them out directly. Yet, they're too retarded to get it.
But then again, leave it to weebs to be absolutely retarded over fictional women just because they look just remotely fuckable to them.
This exactly. Anyone who is interested in parasocial relationships/stalkers and is new to that sort of thing, search up Ricardo Lopez when you have the time.
