I actually took the time to explain to a recruiter that java != JavaScript... He told me they were similar enough... I put it in terms he'd understand: "If you want to make money, you need to understand that they are not similar. If you keep saying they are and send your clients a dev with no java experience, you'll lose clients. if you send devs to a place that's looking for something they don't know, you'll lose devs. Your pitch reeks of desperation and you'll be out of the business within a year unless you actually start listening to the people who know the tech."

I almost felt bad, but... He kept pushing when I said no, haha.
