Bronies were grown men liking a series for little girls
chuubas are for weebs, holofags are weebs
Bronies were overt, invasive, and weirdos about their hobby
holofags are, well they can be weirdos about it but usually not much more than any other weeb. but importantly, we holofags keep to ourselves in chuuba communities (or at most weeb communities) rather than trying to spread brony shit everywhere.
Bronys were also a much bigger thing, chuubas aren't well known outside of weeb communities (but even normalfags knew about those fucking weird ass grown ass men buying horse toys meant for little girls)
so tell me how (you) think bronys and holofags are in any way comparable
