I generally approve all comments that are constructive and informative; however, I do not feed trolls.  I’ve deleted a number of comments even from those who agree with my positions.  As long as your comment has something useful to add to discussion, it will be approved.  If you just want to make inflamatory statements, don’t bother, I won’t approve your comment.  One troll has repeatedly made comments and listed the email address as f@you.com.  I was an adolescent once, I understand such things.  But please, be constructive and thoughtful in your comments.
