Even if they (religion and culture) sometimes seem as if they are hopelessly tangled together, at least in so far as certain traditional practices are concerned...doesn't it make more sense to simply have no laws concerning what someone wears so long as it applies universally or regionally on some kind of decency scale and leave all the rest up to personal preference?...as opposed to making laws specifically designed to isolate and increase cultural tensions?

Removing religion isn't a feasible solution to this cultural issue imho.
