"This points to another tactic that should be made explicit - the use of Western legal structures, namely constitutional rights, to culturally destroy the West."

You've got it backwards. Western culture affords individuals the maximum amount of personal freedom possible. And typically our courts will uphold those freedoms when governments seek to limit them.

On the other hand, there are westerners who don't value the freedoms we have. They'll try to take them away in an attempt to make everyone 'culturally correct.'
