That'san ambiguous sentence.
You would have been better to type, 'There is no reasoning with someone who is unable to reason.'
As it stands, you leave open the possibility that reason itself is the thing that you are stating must be present (rather than merely the ability to reason on the part of he with whom you are arguing).
3/10. Must troll harder.
