do the signs themselves have a monetary value? if not, then that is not a conceptually accurate way to sign that.
idioms in general dont interpret well, you would have to explain the idea behind it.
regarding the original topic, i dont think its any different than and black person calling anyone white a rascist for the same things. the things that white people do, they do because thats the way we've been taught, we function and think a certain way based on the culture we are raised in, just like anyone else. I would say most of the things white people get blamed for being rascist, they do unintentionally, and not nessecarily out of ignorance, they just don't view the situation the same way a black person would, because we do not have shared expierences that make us think the same way.
same with Deaf/hearing. these two groups both have very different expierences growing up, that formulate our opinions and beliefs. A black person is not inherintly right simply because he is black, and a hearing person is not inherintly wrong because his ears function.
the balance is struck when people stop using labels to seperate themselves, and sit down and have an open-minded discussion and learn about something other than what they are comfortable with. This includes Deaf people too. playing the victim only makes people think you need to be saved.
