The ignorance of this statement pisses me off.
I am a social worker and work with people who have been verbally, emotionally, physically and sexually abused pretty much every day. There is a difference between "experiencing life" and being abused. There is a difference between your dad calling you a dumbass because you didn't fill the car up and your dad calling you a worthless piece of (insert whatever you want) everyday for the past 10 years.
Abuse is over and above what is considered normal. For example, when I am working with children, I look for whether or not a parents behavior has affected the physical, social and emotional development of a child. When you find a 5 year old who weighs 30lbs and can't walk and isn't able to talk yet, then you are dealing with abuse. When you have a 7 year old who has scars on his back because his mom beats him with an extension cord, then you are dealing with abuse. When a two year old has a broken arm because mom was holding him while her husband beat the crap out her because he was drunk, then you are dealing with abuse.
/end rant.
