You didnt. If you cant work it out.....I'll explain.
He took one of your comments (which were uncalled for) as YOU calling him a liar. He took what you said wrongly, and because he is trying to enquire about joining an established team, was worried that he now looks bad because of your comments, and I was trying to let him know that its all good. Well done with contributing to his thread.
Next time you write a job application, post it to me and I'll scribble all over it for you, and foreward it on to the company.
(tl;dr GET OUT OF HIS THREAD.)
