Islam can't coexist with any other religion or civilization because it's deeply antagonistic by design. The topic here is Christianity but the same logic can be applied to Hinduism, Buddhism, Sikhism, Judaism, etc.
Women should not be allowed to wear burqas in public. Because if we let them, then we're admitting that it's okay for men to wrap their women in garbage bags. We're participating in the persecution of women.
So, no burqas!
