That's probably about the best way to define Western Otaku (s). There was a huge rift between who were the Otaku and who were the Weaboo. YouTube has provided a little insight into that (if you watch an anime cringe video and you're an anime fan...you'll see that what people do in those videos is just not normal). I think it's nice to collect a few figures, hard copy anime, JP-RPGs or visual novels, reading manga, and even to discuss it publicly as a large point of influence. I think where I see the weeb line get crossed is when someone (Westerners in this case) gets into anime and believes they are "transitioning" into a Japanese person. They start buying Pocky, they wear cosplay into public places (saw someone do this in my music shop back in the States), they start uploading videos of themselves trying to sing J-Pop on YouTube while dressed in cosplay, they become a homespun martial arts expert and aren't afraid to don a Naruto costume while attempted to cut plastic with a fake katana. I mean, you can do those things without crossing the weeb line but it seems the younger audience really falls into that area. 7-years ago, I did not hear anime fans referring to themselves as Tsundere / Yandere and the waifu thing just popped up in the past 10-years. I'm not judging but many who go to the extremes often call themselves Otaku. I believe they give a bad name to Otaku. Maybe it's just something about the age, too. I guess I was probably a bit exaggerated when I was a teenager, too. I like anime the same today but I can't say that it shows on my public image.
