Most people in America don't have the privilege of getting swimming lessons with normal attire on their bodies. If a person goes to their local swimming lessons place and demands the intructor teach the class to swim with pants, skirts and shoes, he's going to get denied.
So does the parent not have their kids learn how to swim? What if the dad is too busy with work to teach them? Not enough income to have their to own deep swimming pool? The wife shouldn't left alone to teach the kids to swim outside of the home. So do the kids go through life not knowing how to swim and risk drowning if they fall into a deep body of water? All because SSPX's version of swimming is too "naked"?
Don't hang out on or near the ocean and you'll be fine.
Oceanfront and lakefront property is several times more expensive anyhow. It's a luxury most Catholics can forego. If eternal life is a priority, that is.
If you're going to be a sailor for a living, then yes, learn how to swim. Most people live inland (and ON LAND) all their lives. I'm not going to be dropping into a large deep body of water any time soon. I never learned how to swim and it hasn't been a problem for me yet.
Like I said early in this thread -- Americans think children are defective or deprived if they A) can't swim and B) don't regularly swim in a large pool. Why? We're human beings, not fish. Get a kiddie pool or one of those family sized above-ground pools for a
few hundred dollars if you MUST experience being surrounded by water. Everyone can afford that.
If you are too busy to teach them to float, swim, etc. in your $300 backyard above-ground pool, then they aren't likely to need to know how to swim anyhow. You're obviously too busy.
