HoloJP's fanbase and members at least treats them like an exotic treat so they don't hate them.
The difference in mindsets mirrors the company exactly. NijiJP hates the west and treats them as a shitty forced side project, while outright refusing to market the JPs outside or the ENs inside of Japan. Holo treats all of the holos as one major entity and has no issues with cross promotion or interbranch collabs, if not encourages it.
