You are completely over the top. In your world, any man that doesn't stand up and say "F You" to everyone that disagrees with him is a pussy. While I have no problem with the wife-beater term for those t-shirts and refer to them as that myself, I am not so narrow minded as to not see how it could bother women who have been beat by their husbands. Given that refering to them as just t-shirts would not hurt his business at all, it becomes a matter of not making this the hill you die on.
"You are completely over the top."
And you continue to miss the point completely. I'll try one more time, then I'm going to hit my pit.
"I am not so narrow minded as to not see how it could bother women who have been beat by their husbands."
Bing, bing, bing, bing: false dichotomy alert. In your world, a person either agrees with the complainers or is "narrow-minded."
Sure, I understand how it could bother them, and I also understand why being bothered by it gives them no standing whatsoever to demand that others change their behavior.
In a just, sane society, a person has to have legitimate grounds to demand that others do or stop doing something. And "Any mention of wife beating offends me because I am hypersensitive beyond all rationality" does not constitute legitimate grounds.
Those shirts are called "wife beaters" because the cultural bigots of hollyweird have made them a cliche. It's a farging joke, fer corn's sake. And we all know what you're supposed to do when people can't take a joke.
"Given that refering to them as just t-shirts would not hurt his business at all"
Sure it would. I wouldn't shop where they didn't know the difference between a t-shirt and a sleeveless undershirt. I don't like to buy from morons.
"it becomes a matter of not making this the hill you die on."
There are times when that is valid, and times when it is only a mask for cowardice. Besides, the notion that this could turn into a hill that men die on rather contradicts your assertion that the battle is not worth fighting.
We really need to pick one of these hills pretty soon, tell the chronically-offended community that they're just going to have to shut up from now on, and make it stick -- even if we die on that hill.
