The men would do things like going golfing and the women would go shopping which isn't good for the couples. Which he is right.
No, it's not. If at all, the amount of JWs who can actually afford a vacation is minimal. When you consider the type of vacation that they would choose, typically visiting the local congregation and winding up preaching with them, I don's think that anyone would even consider going shopping or golfing. Seriously? How many JW golfers do you know? If at all, there are very few. And how many JWs do you know that can have shopping as a hobby (not that shopping as a hobby is a good thing, anyway, but still)? So why are they talking about activities that at best apply to a very, very small group of their people, if at all?
But I was thinking that maybe his motive for discouraging couples vacationing together is to discouraging couples from sharing each other with the other couples and I don't mean men golfing and women shopping. He just wouldn't want to say that there may have been reports of mates sharing each other.
That sounds more like it. This kind of filth is what a lot of Christian religions love spreading. They have to be told that because apparently that's the only thing to do in this planet when you go on vacation. Apparently, to them, vacation has this magical effect that makes you forget that you're a well trained Christian with good values and morals, and chose to live according to certain values and standards of living.
