Asking for a recommendation from friends/family is best, even if their lawyer doesn't specialize in employment law. In the case where the lawyer doesn't do employment law, say you were recommended by a friend/family and ask them if they can refer you to a lawyer with the right expertise.
Failing that, contact your state bar association. For example, the CA bar association offers a list of certified lawyer referral services that will help you find a lawyer with the right expertise: http://www.calbar.ca.gov/Public/LawyerReferralServicesLRS.as...
I don't think the objection is to being direct. It's to dramatically expressing contradiction when you are in fact agreeing.
Next time try something like, "Yes yes yes, definitely find a specialist employment lawyer. Referrals and the state bar are a good way to do that, but make sure you end up with somebody who has spent a few years dealing directly with cases like this."
At no point does he say to get advice from that non-specialized lawyer. He even says that if the lawyer doesn't practice employment law, to simply get a referral. What more do you want? A massive billboard with "only use employment lawyers here"?
