i am nit denying that there is discrimination, I'm just pointing out that on average the discrmination goes the other way in recent decades. i am (was) a tech worker. I'm now too old to be hired - another discrimination problem.
if you do a bit of reasearch, you wil find some horror stories from men who are or tried to be elementary school teachers. also, nursing is female dominated and I've seen a few unpleasant testimonials. don't have verfied numbers at hand, but thise shoukd show therlther those are edge cases or common.
