You have made mine and other people's lives a misry on this forum with your obsessive desire to "win".
I am not proud of feeling satisfaction in turning the tables, but there it is - we all have ourr weaknesses.
Obsession is when you insist on repeating yourself over and over again, long after your questions have been rsponded to.
Obsession is in attempting to prove wrong something that is self evident and log accepted.
Obsession is in believing you are right and everbody is wrong or "ignoramuses" i=or muppets, then going off to complain e=hwen somebody responds to you in kind.
And above all, obsession is when you spend huge amounts of effort in trying to prove that you know more than the rest of the world.
I suggest you leave this while you are only this far behind - believe me, it can get worse.
