I do get what @Redux is saying and I can't really say I disagree. By always pointing it out when someone does it, it gives it relevance. We are giving them a platform for free. Remember what people would say if someone was picking on you, or if you know someone is an obvious troll on a social media site. Just ignore them, right? Or in other words . The only reason they do it is to trigger people and get a reaction. By bringing it to light, you are adding fuel to the fire and just making the flame bigger.
