People discriminate every day. When you got dressed this morning, you discriminated against all the clothes you chose not to wear today. When you walk into Baskin Robbins and buy one scoop, you discriminate against all the other flavors. Discrimination, in and of itself, is not unlawful.
Discrimination against someone because of their race, sex, age, religion, national origin, or disability *is* unlawful. If you are qualified for a position and are not hired because of any of those "protected classifications," it is unlawful discrimination. Otherwise, an employer is free to pick and choose whomever they want --- regardless of whether that's the best choice or not.
Remember, you cannot get legal advice over the internet any more than you should take medical advice from a doctor who has not examined you. This site is designed to point you in the right direction. You have to do the rest. Our dialogue does not create an attorney-client relationship.
