No i don't hide my power level,. If a conversation brings up an opportunity to talk about anime, I'll do it and say everything I have to say that is appropriate for the conversation about anime, how I watch it, and talk about it. No, I don't parade around screaming "I love anime, western shows are trash" because i'm not a retard. I stay away from weeaboos because they cannot restrain themselves and I can't bear talking to them while knowing they act this way even though I usually have seen way more anime than them.
If you need to "hide your power level" in public, you are obviously doing something wrong with your life, as you're basically afraid of yourself, you stupid fucking weaboo.
also, i don't give a fuck if i have an anime item in public, it's never something ecchi and weird so i'm fine.
And if you have something ecchi and weird, be sure i'm judging you and i'll be as far away from you as possible
