@ MartianOddity;
Well, you know... now that I've written this out, I should take back what I said completely agreeing with Rekhyt, my situation is a bit different...
As for me, Pocket Monsters is indeed one interest of mine that I'd rather keep in my back pocket, but for more reasons than "reputation". When I have my family barking down my neck to grow up and move on from this, I don't want to go to school (I'm currently in virtual school, but when I go back to public) to deal with the same crap there. Look, I got sick of standing up for it, I tried that, I did that in middle school and didn't work out, so I put it away, kept it a secret from then on. And then left it for four or so years, from boredom / lack of interest, but came back when I transferred over to virtual school about a year ago 'n' found out about generation IV 'n' stuff searching the net. :P One of those on 'n' off phases Pocket Monster fans usually have, I suppose.
Pocket Monsters isn't that significant in my life to change my entire self or image, but when I go back to public school, it's just me to not going run around "I love the Battle Tower :F" like say, er... here on PC. And another thing is... it's because it's so rare that people like it. Why should I go spouting I like the interest if there's not a soul to be seen to share the same ground with? At the high school I transferred out of, I didn't see anyone. So no real opportunity to even mention it, either. And I'm not the person to go around asking people their interests, regardless of topic, that's just being shy. XD
And I saw people admit they liked it, that was in middle school, years ago, when I fought back. And in later years, when (I thought) I left Pocket Monsters for good, of course I wasn't going to fight with them for an interest that became boring to me overall. So you're getting the wrong idea there, and that's my bad for not being clear on my situation. And well, I haven't seen people admit they Pocket Monsters it in the past two high schools I've been to, and doubt the third.
Again, I don't "fake" my interests, no, I merely keep one card face down. (Is that faking?) I am the real me, but I merely put one of my childhood interests away from the spotlight. Although you make it sound that it's one of the biggest deals I have on my plate then, 'n' maybe you're right, but at the moment, my life is absolutely fine without saying "I enjoy watching the Pocket Monsters Anime, or that I enjoy figuring out successful strategies in the Battle Tower!" to people that I can't relate to on that topic, and may not care.
