Well, I'm not an ex but the people who are part of FCDC for the most part now are unhappy, mean, and focused more on shaking people down for money to pay for their "ideal org" than anything. Personally, I have had cameras shoved in my face. I've been followed on the metro on at least three occasions where I've actually caught them and I've witnessed other people, including minors, being stalked by Scientologists after protests. I have been insulted, threatened with physical violence, and screamed at on the street. I know people who received threatening letters accusing them of being terrorists in an effort to harass, slander, and intimidate them. These letters are sent to the parents of protesters, to college students, and even to exes at their place of business in the hopes of ruining their reputations in front of their bosses and co-workers. I have been physically assaulted by a Scientologist only a month ago right in front of the building while other Scientologists took pictures of the attack and everyone involved has refused to cooperate with the police in finding this guy who is believed to be named Greg Layton, an OT8. There have actually been two assaults in FCDC recently, I have also witnessed physical attacks on other peaceful protesters resulting in the charging of Scientologist Reinhard Koening with simple assault. He is facing a large fine and up to 180 days in prison.
They're not rumors, that's what I've seen with my own two eyes. And FCDC is MUCH tamer than the orgs in Florida and California. Maybe they still believe they're trying to help, but that since we're "suppressive people" and according to LRH don't warrent human rights, we're an acceptable casualty in their attempts to clear the planet.

If you're ever in town, stop by for a visit at the org and see what happens when you start asking questions. If they don't lump you right into the same "terrorist nazi communist KKK german psych funded marcabian death cult" genre as the rest of us, you'll see some angry, volitile people ready to lash out at whoever is around.
