I see it like this, if you are going to borrow something from another culture, be sure to understand the meaning of it.
For example, take the person who wears a T-shirt with Kaali-Mata on it.
SMART PERSON: "This is Kaali, the Surpreme Godhead in feminine form as the Lady of death, time, transformation & enlightenment. She's the benevolent, fierce but loving mother who destroys all ignorance & wickedness within & without and is the equal partner & spouse to Lord Shiva."
STUPID PERSON: "I got this shirt cuz it's like totally 'metal' with this scary blue-skinned naked demon babe!" OR "I got this Kaali shirt cuz she's the ultimate man-stomping RadFem cuz men are yucky & she kicks men's ass!" OR "I have this Kaali shirt cuz she's a SUPER-DEMON! HAIL SATAN!"
And I agree about that goofiness with writing random words in an unfamiliar language/script.
