Final answer:
No, sexual orientation is not a protected class under Maine Fair Housing Law, but federal legislation now protects employees in the private sector from discrimination based on sexual orientation and gender identity.
Step-by-step explanation:
No, sexual orientation is not a protected class under Maine Fair Housing Law. However, federal legislation now protects employees in the private sector from discrimination related to sexual orientation and gender identity, based on a 2020 Supreme Court ruling regarding the application of the Civil Rights Act. It is important to note that while federal law provides protection against employment discrimination, housing discrimination is not explicitly addressed at the federal level.
