Common sense logic 

How can you be sure that you are right if you have never heard an explanation of why you could be wrong?

PS: Conflicting views prove that Freedom of speech is alive and well. But current history almost banished that fundamental right. Speak up and out. Dare to protest and shout. Unruly should never be, protesting should be calm and bright, danger when stupidity becomes a right.
