No, they just think that the Japanese/Otaku culture is superior and want to enjoy it in their own way.
Many people I have talked to over the years have called me a weeaboo for my rare use of Japanese and periodic acclaim of Japanese media, but overall I really only watch Dragon Ball and the rare Miyazaki movie. To this day i still think Grave of the Fireflies is the best animated movie of all time and that Japanese culture is amazingly complex.
