Which constitute discrimination or harassment?

There are some other exceptions.

Your list is too broad. Sexual orientation, political affiliation, veteran status are not protected. Not all discrimination is illegal.

Harassment and discrimination are simply two terms, each distinct, and each of which has a broad range of definitions and applications; applying these two terms properly to determine if anything illegal has occurred always requires a specific context and a specific set of facts. Consider: in each and every choice any person has ever made, or will ever make, they have technically discriminated. If I choose to wear a green shirt instead of a blue shirt, say, I've discriminated as to color. So, it's not that discrimination across the board is illegal it can't be but to use a somewhat circular argument (necessary because of the lack of context) only illegal discrimination is illegal. The legal concepts of illegal discrimination and illegal harassment can come up in a variety of contexts in almost any area of life: housing, employment, domestic relations, etc. What is and is not illegal very much depends on the context of the situation, as there are far too many nuances in the law to be able to adequately address what may or may not constitute harassment or discrimination. If you feel you've been illegally discriminated or harassed, you should contact an attorney in your area for a consultation.
