Why do fandom blogs hate hipster blogs?

On tumblr, I've noticed like all the fandom blogs seem to be in agreement that the 'hipster' blogs are some sort of massive amalgamation of shoes and iPhones and overly deep pseudo intellectual text that's really meaningless, and I wonder why? Sure, those things do crop up every once and a while, but not often, and why bother with the hate? I mean, 'hipster' blogs largely just leave you alone and don't bother anyone. Can someone fandom-y tell me why this is?

Everyone hates hipsters, and their blogs

They are both fighting over the title of biggest douches in the world.

  • Why do so many people hate on beats by dre? I paid 350 and the sound quality is amazing on my iphone 4s. People say they are a waste of money, but the people who say that is because they can't afford them. The design of the headphones are great so stop hating on them because you know you test them out every time you go to best buy haha.
  • Why do people hate on the iPhone 5 so much? The galaxy S3 does not blow it out of the water. The Galaxy has a bigger screen, SD card slot. The iPhone 5 is built better. They will both run on LTE, have basically the same speeds, the iPhone's camera will be just slightly better. Besides the screen size, it seems more like a battle of iOS vs Android, as how the phones perform will be extremely similar.
  • What would you consider me? Ex jock prep hipster? I buy from mainstream places, but I also love thrift shopping! I love Aztec prints and I wear alot of plain shirts that I accesorisze. I make jewelry and bake. I don't use heat on my hair and don't wear my makeup. I love 2 door cinema club, Edward sharpe, fun, and the fratellis. I love kill bill, the sopranos, weeds the tv show, skins uk and the dark knight. I have a galexy iPhone case. I wear sperrys alot but I also love my converse
  • What are some really good hipster edit apps for iPhone? Any really cool editing apps. I'm in an edit war with a friend and I need to win! Also, does anyone know the app that basically does a 3D effect but it has different colors? Like not blue and red but yellow pink orange red like that. Any helps greatly appreciated!
