That's true. It isn't always possible for someone not trained as a lifeguard to rescue a panicking person. (BTW, the last I heard the best plan is to grab the person by the hair and pull them so they can't get hold of you and pull you under.)
But even if a rescue isn't possible, that doesn't mean you have to turn your back on that person and swim to shore with nary a look back.
As I said above, my husband and I were trapped in a rip current off Malibu. Since I'm the native Floridian, I was much calmer and offered to pull him behind me as I swam out of the current and into shore. He was quite panicked and yelled at me not to touch him.
So I swam a few feet away, all the way back to the beach. I did not turn my back and forge ahead without keeping track of his welfare.
Yes, everyone is different and GG is under no obligation to react the same as I. But come on...
And pardon my latent sexism, but even today men are socialized to be somewhat protective of females. (Didn't GG even have the gall to describe himself as RG's "protector" on TV last night?) What sorry excuse for a man swims off and doesn't even keep track of his female companion in the water?
