I've decided I'm not going to text her back
Can you tell me why you won't text her?
I want them to see how it feels like to be ignored by a girl
While you don't have to respond to every message that you get, it is extremely rude to ignore people on purpose. Leaving them on read when you can easily respond just to prove a point is very petty and will make you no friends in life.
I love being a hater.
If it is important you need to reply. Ignoring people is childish and won't get you anywhere. If you want to be known as a hater don't expect your friends to stick around.
