Final answer:
Kathleen should consult with her broker about refusing the listing, as complying with her client's discriminatory request is illegal under the Fair Housing Act and goes against professional real estate practices.
Step-by-step explanation:
In the scenario where Kathleen's seller client Joe instructs her to show his property only to Hispanic buyers to preserve the ethnic character of the neighborhood, Kathleen should take specific actions that comply with anti-discrimination laws. The Fair Housing Act prohibits discrimination in housing based on race, color, national origin, religion, sex, familial status, and disability. Therefore, Kathleen's best course of action is B. She should consult with her broker about refusing the listing since complying with Joe's request would be illegal and unethical. Choosing any other option would involve participating in discriminatory practices, which are against the law and real estate regulations.
Discriminatory practices like the ones Joe is suggesting were once common and have had long-lasting impacts on communities. They perpetuate segregation and deny equal opportunity to housing. It's crucial for real estate professionals like Kathleen to uphold the law and work against such practices, which can also have broader implications on employment discrimination and social equality.
