Miscavige is not as much of a coward as Hubbard was, he will stick out a little long, Hubbard would run and hide at the drop of a hat. Hubbard was spineless to the core, it got to the point where he only directly communicated with 12 year old girls ... The Commodore's Messenger how fucking creepy was that
I don't know DM, so I don't personally know if he is braver than Hubbard.
If he is, then more fool him, because you are right, one of Ron's key attributes was cowardice. It kept him safe from arrest and, yes the 12 year old girls scenario is creepy!
If DM is being braver than LRH then he is even more of an idiot, because LRH's black magic spell is doomed to always attract interest from legal authorities and a brave LRH impersonator is truly an idiot!
The best LRH impersonator will win the most power in the Scn field, whether it be in the CofS or Freezone. If Rathbone and/or Rinder are closer LRH clones than DM then they will win the most power. Poor doomed fools!
