Just as no one should be denied housing on the basis of race, no one should be denied housing on the basis of sexual orientation, gender identity, or gender expression either.

Pennsylvania has a Republican problem that will likely allow such discrimination to continue, but the bill itself is essential; hopefully it gets submitted again once the Republicans lose their Pennsylvania Senate majority.
