Well, it depends on what people are offended about.
If they're offended that a shirt exists somewhere, anywhere, saying to rape someone then sure, there's probably no difference here.
If they're offended that some asshole went out of their way to make a shirt talking about raping people then it's a bit different. There never was anyone who went out of their way to make a shirt. This is the near-equivalent of running "rm -rf * /" to remove only sub-directories and accidentally inserting the extra space.
So should they have checked their verb list better, or thought more about the possibility of what their algorithm would generate? Absolutely! But their sin was not nearly as bad as actually thinking that such a shirt would be acceptable to make.
