Why does everyone hate LA so much?

I’m being serious. I’m not looking for answers along the lines of, “Becuz it SUX!”

Yesterday, I was in the airport and told someone I was going home to LA and he said, “Oh. I’m sorry.” What’s the beef? I used to be sort of a hater myself, but now I’ve grown to love it for what it is. Maybe it’s lacking in some ways compared to SF or NYC, but why can’t we just appreciate it for what it is? Or is it just trendy to hate LA? Thoughts? I’m interested in opinions from both inside and outside LA.
