I would get opinions from maybe five attorneys who specialize in discrimination. If none want your case, it may not be feasible.
My standard disclaimer: I am not offering legal advice, assume I do
not know the law in your state or at all for that matter and that I am
just making suggestions for starting points for when you do speak with
an attorney. Do NOT rely on anything I write and contact a lawyer in
your area immediately after reading my posting.
Oftentimes, what you may feel is a clear case is not so clear to an attorney, who both knows the law and is divorced enough emotionally from the situation to look at it clearly. Moreover, even if there is liability, the damages may not justify a case if handled on a contingency-fee basis.
