I wouldn't say the Sailor Moon fandom itself is bad (granted my only real experience is here and I barely post) but I will say some of the more casual fans dismissing any other magical girl anime as a Sailor Moon rip-off or thinking this series invented the genre is hella annoying.
I say this because I used to be that type kind of. Never thought other magical girl shows were rip-offs or that this show invented the concept, but for a while I did dismiss them as being inferior.
1st off I REALLY LOVE your Cure White Avatar, Love Precure Allot and good to see other Sailor Moon Fans that enjoy Precure!
Never Really in my Life thought in the Least that other Magical Girls shows where rip-offs of Sailor Moon, I Always saw them and I greatly encourage other Fans as well to in See them as one of the GRANDEST parts of Sailor Moon's Legacy, they the Franchise and Characters Litterly where the Originators of a WHOLE New Superhero Mythos and Style of Magical Girls!
Nearly Everyone One of these Shows tries IMO to seem to Honor Sailor Moon and What Sailor Moon Did and I LOVE the fact that Sailor Moon SO changed the world is such a positive way like this, creating this class of heroes that IMO is the Best Class in the World, the Magical Girl Power Class!
Yes I will always see Sailor Moon as #1 and will want Sailor Moon to have more story, shows and legacy given to the franchises, but just seeing what Precure has done and others franchises and even American Comics as well have taken notice, that Sailor Moon Changed the world and that is all for the better buy creating the World of Magical Girl Heroes!!!
