What’s important is to reason, reason for anything, behind anything, in favor or against anything. Because it is reason that ensures a rational behavior, development of society, freedom and existence of humanity as a whole.
Slavery, crucification, rapes are all wrong is a general notion now but it took reason from some enlightened people to make it look like that to everyone. Empathy, moral righteousness are all derived from reason and it is reason which creates the balance.
Watch this great talk by Steven Pinker and Rebecca Newberger Goldstein on why reason is important and how it has changed us(society) over the course of history?
So next time you think there is something wrong happening around you understand that your reasoning self is trying to preach you something which needs to change.
