If you don't think reporting it will do any good, then your company has issues and needs to be reported. Harassment on the job should not be tolerated. Where I work we regularly have to take mandatory harassment training. I get it twice as my company contracts IT services to another. I have to take ours and theirs as I work on-site... and have access to our HR and Legal if needed. We are not dealing with some company's feel-good internal worthless drivel, but state and federal law, as you well know. The company has to comply and has to take your report seriously. They are responsible for following all laws and must investigate all reported incidents. You have legal recourse if they do not. Yes I know you know all this, and I am sure your employer knows as well. They need to follow it.
A co-worker of mine many years ago at a previous job was harassed by a much larger male co-worker who actually threatened physical harm to her verbally. The owner of the company (family owned retail business) basically told her 'it's only talk and he is the best salesperson so go away and have a nice day.' The harassment had many witnesses including myself, and she felt she was in physical danger from this man, so she quit out of fear and sued the company and yes they were legally responsible. They ended up firing the man but it was a bit too late to save themselves from legal action.
