Your best defence is a good offense. Send them a letter in the mail
informing about the pedophile coverup, UN affiliation etc. In it mention
it's going to lots of other people around there too. To take the heat
off yourself send it to not just them but some other people they also
know. And one to yourself. If they ask if you sent it to them say "do
you mean you got this too?" and hold it up. Wait a month, send another
letter but in a different-looking envelope. Keep seeding and watering lovingly
with the real truth. It can liberate lots of people and save lives. Even those
who don't quit the WTS may at least contribute less of their money and time
to the the WTS, idolize its dictators less. See? Believe me, this works.
The Bible does say, the (real) Truth will set you free!
