A hedgehog is a harmless British rodent that is covered in quills and shuffles about late at night looking for earthworms and saucers of milk that kindly old ladies leave out for them. They are harmless to any animal that wishes them no harm because there only method of defense is to roll into a ball and wait for the preditor to go away. Unlike the porkupine, they cannot project there quills.
I identify with the gentle hedgehog. Most English people do. We are a nation of hedgehogs.
Scientology doed not identify with the hedgehog at all. L Ron Hubbard thought that nothing could be defended and that the only means of defense was attack. Accordingly, all of scienntology is designed to intimidate. They have some very formidable weapons.
1) The Noisy Investigation. This is a loud, public investigation into the critics business that is designed to embarass and discredit.
2) The ad homminin attack. To discredit and upset.
3) Picketing and leafleting your neighbourhood.
4) The harassing lawsuit.
5) Personal attacks on your charicter on the internet.
6) Fair Game 'Tricked, sued, lied to or otherwise destroyed'
7) PC folder blackmail.

Victimisation of relatives still in the cult.
9) Behind all of this the threat of 'R2-45'(the 'joke' policy of blowing critics brains out with a Colt 45)
This is a frightening and repellant combination. The natural reaction is to lash out verbaly in an effort to protect your family, or to hide.
Both these reactions tend to backfire. One person had to leave the USA as a result of a relitively mild joke about an ICBM. The cult is simply better at being nasty than any healthy person can be.
Let us look at the alternative. How about being really gentle? How might a hedgehog counter all this agression?
1) The Noisy Investigation can be countered by joining the local residents association and being honest about your problem. They will support you. Your union and your employer will also flock to your side. Nobody likes bullies and you will find friends at every turn. The important thing to remember is that the issue is not the rights or wrongs of the cult. The isssue is bullying.
2) The ad homminin attack is only made by people who have run out of reasoned arguments. The fact that scientology starts off the debate with ad homminin attack tells people more about scientology than you could ever do.
3) Picketing your neighbourhood will create more enemies for the cult than you could ever do. There is a tendency to unite against outsiders causing trouble. Your neighbours will rush to your side.
4) The harassing lawsuit. This will not work provided you remember the isssue is not there right to believe stupid things (they have this right). The issue is your right not to be silenced by thugs and bullies. This is an absolute and unconditional right in all democratic societies. There is no room for harassing lawsuits provided you stick to this theme.
5) Personal charicter attacks on the internet serve only to pprove any points you may be making about the bullying nature of the cult. They can be used as evidense of harassment.
6) The Fair Game Law can be made into a liability for the cult. Once you have made the authorities aware of this policy then anything that happens to you will be laid at your door. They will pray each morning that you are not assualted or mugged because this would cause a police visit to your local org.
7) PC folder blackmail is illegal. It also has the effect preventing people from volunteering for auditing. If you have the courage to call there bluff then they will always back down.
