Multiple Los Angeles Fires: Origin?

Questions:

• At how many different areas, some separated by several miles, must fires break out, before we are allowed to mention the mere possibility that some or all were deliberately set? Five? Ten? Any number at all?

• At what point are ISIS vicious enough, or environmentalists fanatical enough, that we can dare to question the origin of the Los Angeles fires without risk of being diagnosed as paranoid at put on an involuntary psychiatric hold?

• How deep must the suspicion run before we feel the need to look up the antonym for paranoid, so we can use it to describe those who believe that high winds are the sole possible explanation for the wildfires? Would it be naïve? How about trusting? Perhaps sheep-like? Head in the sand? Lacking in situational awareness? Or just plain stupid?
