Although I'm happy to read that you are open to the truth, your comment also shows just how effective Bilbo's propaganda has been. Don't you understand that you base your comment on a book written by Bilbo himself? They didn't want it, you say? How do you know?

The sad truth is that we cannot make an objective reconstruction of what happened when Bilbo returned. It is however obvious that Lobelia moving into Bag-End was absolutely logical and that if she was angry, that can easily be understood. It also is obvious that Bilbo greatly disliked Lobelia. With this information we must try to understand what really happened. It is a hard battle we must fight, but in the end, I am convinced that truth shall be victorious.

going by your theory

You misspelled "truth".
