Normal is subjective to whatever life experiences you have gone through and the beliefs that you have grown up with or adapted on your own. What's normal on one side of the world would not be considered normal on another side of the world.
Everyone is entitled to an INFORMED opinion. Some idiot yammering because they like the sound of their voice should STFU.
Why does there have to be a right and wrong. Life is not black and white. Life is very colorful at times and grey on other days.
