To recap and conclude (think this thread is coming to a natural end now)
It's all about liberty and how the Burka represents the complete antithesis of the democracy which this country fought/evolved long and hard for. By allowing such an extreme application of an anathematic religious and cultural stance to take hold is a threat to those things that make us what we are. Therefore, paradoxically, we have to "force" liberty upon those that do not want it.
