When a government challenges JWs' freedom, it's not unusual that they (wherever they can do that) organize a campaign of sorts to protest, affirm and defend their religious freedom (see, for instance, the recent campaign in Russia http://www.jw-media.org/rus/20100226.htm and the 1999 campaign in France over the denial of tax-exempt status to JWs http://www.rickross.com/reference/jw/jw6.html).
One of the reasons of concern such campaigns focus on is the threat implied for other religions by the government's behaviour with the JWs ("What will happen tomorrow to other religions?").
But do they really care about what happens to other religions? Have you ever seen JWs campaigning to defend the religious freedom of some other group or denomination whose activities are prohibited or somehow hindered by the secular authorities?
If they really cared about religious freedom (not only their own), wouldn't they do just that?
