Whether or not you can reason with someone depends upon how you react to them. Obviously, if you are being raped then the time for reasoning is long past. But so long as we are talking to people over the internet, then it seems that our ability to reason with someone is at least partially derived from our own beliefs about them.

It is hard to reason with someone when the conversation is "one way" and everything they say is tainted by our own bias. If our bias says they cannot be reasoned with, then we will not even attempt to understand what they are saying.
