Orlando...

Let me express my condolences for the dreadful tragedy that has overtaken your town.
It defies rationality.
The why is the difficult problem.
the killer was a paranoid which is a defence against passive unconscious homosexuality.
Paranoids kill because they unconsciously they know they are gay but cant admit it so the act of repression takes more psychic energy than can be mad eavailable to the ego and consciousness.
Forget about the other stuff. get to the nub.
And it is to be hoped that after the shock has worn off that America will be made sane again.
