I'm going to come out and say it....
I am not a one direction fan, but if you don't like them, you are a hater, simple as that. You HAVE to admire what they are doing (prepare for a lecture), and this came to me whilst watching that documentary Mad about one direction or whatever it was called on C4, having never listened to them before.
I also know what I am about to say sounds very harsh, but it is if you think about it, very true.
Basically what these group of young guys are doing is creating music which is massively financially rewarding, because they manage to take so many young girls for a ride.
Basically if you listen to any of the songs, they are singing about how, even though the *girl* is not all that, or not the most popular, or not the most beautiful, they still want to be with her. As a consequence they have managed to get a very large amount of (sadly) young girls who are unsuccessful or undesirable to follow them fanatically, to the extent where many of them envisage that they have a relationship with them, have a favourite etc.
It's a massively brilliant thing they have done from a marketing point of view, the "stunning" girls will be going for the footballers etc, but these girls are an untapped market, and they have basically catered this market perfectly.
And that, is why you have to admire what these guys are doing.
