I found an example online where a stripper in Nebraska sued for gender discrimination, though that case was dropped too.  

This type of discrimination may also occur in conjunction with the other protections of the Fair Housing Act against race, color, religion, gender, disability, and family status discrimination."

Here is the Seattle definition: “Discrimination” means any conduct, whether by single act or as part of a practice, the effect of which is to adversely affect or differentiate between or among individuals or groups of individuals, because of race, color, creed, religion, ancestry, national origin, age, sex, marital status, parental status, sexual orientation, gender identity, political ideology, honorably discharged veteran or military status, alternative source of income, participation in a Section 8 or other subsidy program, the presence of any disability, or the use of a service animal by a disabled person.

I know the new thinking is gender neutral and we are all the same, but men and women are different.

If the tenant meets the credit, income-to-rent, etc. ratios and you reject them (only after the interview), they could sue you for violation of Fair Housing --> claiming that it was only after meeting them in person (their race, gender, etc.) ... that made them unqualified.

In the last 2-3 months HUD came up with new guidelines regarding against criminal background as a protected class such as race, gender, etc.  

Every group is going to have bad apples, regardless of their race, religion, gender, socio-economic status, etc.  

We do not discriminate against persons because of race, color, religion, sex, handicap, familial status, national origin, age, sexual orientation, or gender identity.

Why any of these guys are listened to with anything but disdain is beyond my comprehension.Respectfully,Gary   In America (left wing narrative), there's always self-generated issue that's almost always 'man made', such as these "global warming", or "animal cruelty so lets not eat animal product" or "same toilet for every gender" while they are ignoring the very first problem that people facing like "rising criminality" and "rising violence in highschool".
