Why aren't people allowed to dislike iOS 7?

I personally like it...it has its visual flaws here and there but that'll be fixed in time and it is definitely more refreshing than iOS previous. But I've noticed on many tech sites/Apple sites (ESPECIALLY Appleinsider) that anyone who doesn't think iOS 7 is the best thing evarr is immediately branded a troll or called names or bitched at until the cows come home.

While this type of reaction is customary among a lot of fans (Tech or not), in the tech sector Apple fans seem a lot more venomous...
