I groan at the stupidity of having to explain this, but here goes:
Surely you can see there is a difference between a Jehovah's Witness getting involved in politics and the Society using a secular organization to defend their right to free worship.
The distinction would be clear to any Witness not tainted by years or reading apostate bile. Jehovah's Witnesses will in good conscience do whatever "furthers Jehovah's interests", including using secular organizations and governmental agencies to their own ends. This can in no way be compared with a single Jehovah's Witness getting involved in politics for ends unrelated to "the Kingdom".
sigh...
