Honestly, every person is different, be they hearing, HOH, or d/Deaf. Some heavies really only want to learn because they think the language seems cool, or that it something to make them stand out, to make them deem different. While others want to learn based purely on the cultural aspect. You know how some people fall in love with say French or Spanish culture? They love everything about it and ultimately learn the language in order to immerse themselves into that culture. Based on the ones who do it for culture I'm very sure they'd love the deaf community and everything we stand for regardless if we had ASL or not. It's honestly based on their motivation for learning the language, and if they truly care about or respect the culture at all.
