As long as you show people that you have other interests besides animu and lolicon, and as long as they know that the loli is DRAWINGS and that you aren't out molesting children, it's fine.
Myself, a female anon, I hide my powerlevels in public, when I'm near strangers. But with my boyfriend and his best friend I force them to watch Gurren Lagann and any other animu I think he'll enjoy. Actiony stuff, basically.
I have to watch the lolicon in my own time, because he's not interested, but that's okay too. It's not a secret that I like lolicon, and we constantly make jokes about how much of a raging pedo I am.
Also: I have a lot of anime merchandise, but even more manga. I keep them on my shelf with all my books - looking at it, you can see that while I do enjoy manga, I also enjoy non-weaboo hobbies, so no one questions it.
Basically: It's fine to hide powerlevels from strangers, but friends etc should know who you really are, even if it is a failure pedophile weaboo.
