i've already given Harley the link to the Orthodox translation of the septuagint, continuing to say that the orthodox are not translating it after being given the link seems deliberatly posting false information that the post knows to be false.
Calling another poster a "liar" is "attributing motives" and therefore is "making it personal."
There is no problem however in saying that the statement made by another poster is false, misinformed, incomplete, inaccurate, etc. There is also no problem in pointing out that the poster is repeating the same false statement.
