I appreciate your concerns Richard, but I believe they are unwarranted in this case fortunately.
First, my impression is that the discussion between was objective all the time and far from being heated up with emotions. Second, looking at the profile of the contributor, one can assert that he might be relatively new to our project, but he is certainly experienced in Open Source development. So I wouldn't worry too much about his feelings 😉 Regards, Matthias
