Lol. So, I've just seen the locked thread in question and what I think is: how much time wasted and how much energy in dismantling a conspiracy that only he believed, right? I see you took your time in dismantling his arguments very rationally, which I see commendable. I don't have so much patience for that. That's why some time ago I used the wonderful ignore button.
Its not "wasted" IMO. If nobody took the time to dissect his b.s. there'd be a lot more forum members walking around with unfair negs on their heads. Its not the first time this has happened by any means. I've had this relationship with him for longer than you've been here. But to rehash it all right now would be the true waste of time. The appropriate measures have been taken (for now), time to move on.
