Your last sentence is key here. I personally think you need to ask yourself when you have the urge to call someone out "does this add value to the current discussion?". If it does, you should lead in with questions like "Have you thought about..?" or "I don't think your example is quite correct, here's why.." Definitely stating "You're wrong, this is how you should do it" is great way to immediately shut the other person down. If calling out the person in question doesn't add value to the conversation, save it for a private conversation later. Simply being technically adept is no excuse for poor communication skills.
