Please do not try to argue with the editor. By doing this, you could successfully put your own self in a black namelist for that or even other journals.

As an editor of a rank B journal, I would tell you some plain facts:

1. To find proper reviewer(s) is one of most difficult tasks an editor is dealing with. Therefore, he or she would alway be thankful for someone accepting review invitaion.

2. To invite somebody as a reviewer implies that you put your trust in and rely on this guy's exptertise and academic virtue. Unless strong and undeniable evidence otherwise appears that proves this guy is unworthy, an editor would  trust him or her unconditionally.

3. Even so, the editor would be partly responsible for choosing a wrong guy. So, to argue with the editor, in fact, is to trigger his or her anger and frustration. You are actually taking fun out of what he or she is doing.

As for your case, I did not see any evidence that the reviewer was unworthy. What I saw is a sore loser, frankly speaking.

Therefore, it is usually meaningless trying to change the decision by the editor. Just move on. There are dozens of other B-ranked  journals. Do not play stupid by doing stupid and meaningless thing.
