Having no tolerance at all is really not suitable for playing Twitter, or you could say a poor mindset that can't accept being criticized. When I first started using Twitter, no one criticized me at all. Later on, because of many things, I was criticized by people for various reasons: some for my wrong words, some for my viewpoints, and some due to my stance. So what to do? If someone criticizes me, I just look for the reason. As long as the criticism is reasonable and well-founded, I accept it and discuss it rationally.
