How to identify a provocateur?

Let's list the phrases peculiar to her or him: 1. "It never happened, you're just making it up." 2. "I'm just expressing my opinion, I have the right to do so." 3. "Are you absolutely sure of what you're saying?" 4. "Prove your point, please!" 5. "Are you saying I'm wrong?" These are the most basic phrases provocateurs give out in order to cause you to have doubts. Of course, after such words, many fall into a daze: after all, everything you said has been argued and proven, but the person still refuses to accept it. Such a behavior can make you feel insecure. Moreover, it can cause anger, confusion and anxiety.
