Which Is the Best Standard-Form Representation of the Following Argument

Which is the best standard-form representation of the following Argument from Analogy?
We legally prohibit discrimination against people based upon their race or religion when they are searching for a job, a home, or trying to access off-the-rack sales and services. We have good reason for prohibiting these forms of racial discrimination--we have seen for ourselves that allowing them leads to the kind of racial oppression common in the American South before the Civil Rights Act of 1968.
Many states currently allow similar forms of discrimination based on sexual orientation or gender identity. In many states, for instance, there is no law prohibiting someone
From being fired because they are gay or lesbian, being rejected for apartment rental because they are queer or trans, and so on.
Discriminating against someone based upon their sexual orientation or gender identity is, morally speaking, no different than discriminating based upon their race or religion. That's why we should prohibit discrimination based on sexual orientation and gender identity in employment, housing, and the sale of goods and services.
