It is. Just because you or your surroundings don't do it doesnt mean it's not real. I can love unconditionally. I will start a blog soon to share my knowledge. I explain this concept further then.
Unconditional love isn't real, and even if it was I wouldn't want any part of it. Part of relationships are give and take, and unconditional love prevents that. Yes you can love your child, even if they go to jail or something, but that love isn't unconditional.
