It might just be that your school is the weird ones. xD
I've faced similar. In middle school. i always voiced what i loved to do in the beginning. Whenever i would talk about runescape, pokemon, starfox, and many more things i loved, all i got was a "huh? whats that?" or "ew thats dorky" response from other girls. The truth is I only ever had 2 girls as real friends that accepted that just because they were dorky liek i was as well.
and i know too well how hard is its to find fandoms at school. I've tried finding people that can show the same passion for naruto and other anime as me. Ironically, the biggest jerk in school loved naruto to death while my best real life friend hated and bashed it all the time.
Though in the end, it really doesn't matter what your friends are into. If you can have a good time with them, even if you are polar opposites like me and my best friend were, then you should be able to put differences aside.
p.s. Usually when someone does bash something, such as MLP or doctor who, they do so because they hear the worst of that series and judge it because its a popular thing to hate. Don't change what you love because of this. just love it even more so! ^^
