"What do you want to do, make non-christains run for cover when you walk in the room? "
Who, me? Read my tagline. I'm just pointing out that modest swimwear is available for those Christians who desire it.
In the USA, lots of Muslims wear the same swimwear as everyone else. Nobody's beating them, as far as I know. We don't have the Taliban here.
OTOH, there are Christian denominations in this country which demand swimwear like I have illustrated.
