Provoking

 Its an unfortunate part of todays society.

Provoking and instagating as it is a joke or fun. People will push and push till they receive a negative action, then become butt hurt because of it. They will claim you should control yourself. 

In reality we have had laws on the books, moral guidelines and other teachings in regards to this before most of us were ever thought of. Sometimes it was called inciting a riot or something similar. So it is nothing new.

Why who knows, usually it is from someone who feels self entitled or the need to make a point where no point exists, maybe just plain mean. 

Just remember when pushing people to the point of reaction, right or wrong there may be no backing up.
