Letter to the editor: One rule for readers and another for contributors ?

Notes: "I refer to your editorial and the statement re: letters ('Dear editor', June 2015, p. 4): 'A surefire formula for not getting published ? Resort to name-calling'. I was very surprised to read, in the same issue [page 14], the article ('Christian Zionism a "heresy", says Anglican priest') by Neale Adams concerning Canon Naim Ateek, and wondered why you do not apply the same principle to people you quote in articles. ... I have never heard of 'Christian Zionism'. Ateek's references to Christian heresy, tribalism and racial exclusivity all seem to me to be name-calling at the very least. Is this one law for readers and another for contributors ?"
