Check out Romans 12:3. By butting in just to look smart and gain a reputation, you are exalting yourself, and not God, even if what you say is in defense of God. Let's please keep this in mind whenever we discuss, whether here, at school, at work, on other online forums, or whatever.
In a nutshell: check yourself and your motives before joining a discussion.
This is a short post since it is only a reminder.
P.S. I used that derogatory "SJW" term here since that's the best way I can describe this behaviour. I am aware of its extremely negative connotations, don't worry ^.^
