My little Pony - Friendship is Magic.
It's really quite simple. Nobody forces you to like it, nobody forces you to hate it. I myself don't like Naruto in people's avatar/sig, but that is their choice and not mine. It is the internet, stuff like that happens every, single, day.
If you like cartoons/animated shows, I'd assume this show is for you, and if you also watched the earlier generations of MLP as a kid, you will probably like it very much. If you don't like cartoons and hate MLP in general... Even then you COULD give it a chance. But in the end nobody forces you to do anything.
It's just funny that people who make such a 'clearly meant to troll' post are actually appalled by the reactions (I'm talking to you OP). And they think we are weird?
Ok, tl;dr ahead (you don't have to click it... But studies have shown that buttons ARE tempting... Hmm):
Of course you may not agree with all this, but in the end one has to realize that it is not a small contingent of trolls trying to force it on you, it's often people who REALLY like the show. Of course there are some who are just trolling, every level of society has it's rotten apples you know... Anyway, I may have posted one or two real 100% trollposts containing ponies (but never any 'profanity'), just because it's fun. I think I'm allowed to after years
of posting in tech support... But I like the show. And not afraid of saying so. So whether others like it or not, I'll show that in my avatar/signature!
