There is a 2-pages article in the Awake! of 8th May 2003 "Does Christian Unity Require Uniformity?". I don't own a scanner, maybe someone can scan the complete article.
While emphasizing the need of unity in matters of doctrine they state
[quote]Today Christians may make decisions that differ from those of other Christians when it comes to matters of employment, health, recreation, or some other area that involves personal choice. Such variety could disturb some. They might woner if differences in outlook could lead to disputes or divisions in the congregation. However, such an outcome is not inevitable.[/quote]
Well, we all know that the WT even regulates such areas as employment, health, or recreation.
Then they add:
[quote]On the other hand, loyal Christians would not insist on their personal rights to the detriment of the consciences of others or at the expense of congregation unity.[quote]
That means: do what the most extreme JW expect from you.
I think they wanted to make it appear that they endorse unity not uniformity. But we who were in know that JW are indeed the most uniform religion.
