The stipulations to receive these funds are as follows:Requirements - Landlords who receive relief funds through the HUD program must agree to the following fair renting terms for a period of 5 years: i. a rent freeze; ii. just-cause evictions; iii. mandatory documentation with any just-cause eviction; iv. no source of income discrimination; v. coordination with local housing authorities to make new vacancies eligible to voucher holders; vi. provision of 10 percent equity to tenants; and, vii. no admissions restrictions on the basis of: 1. sexual identity or orientation, 2. gender identity or expression, 3. conviction or arrest record, 4. credit history, or 5. immigration status. viii.

Sexual orientation is also not a federally protected class; I don't think it's a protected class in NC, but I could be wrong about that. 

It is a completely different thing  to have a callous and arrogant attitude towards things you don't understand, completely trivialize the  significance and prevalence of  rape and sexual assault in our society and the potentially  imbalanced power dynamic between men and women  in this type of situation, especially for someone just starting out ( and is very petite and practically looks like a child), and  to  imply that any assault you have experienced in  life is your own fault.  

The individual was being released from prison on sexual assault charges on a minor.

Quote from @Chris Seveney:I've seen some big ones in the news, but they are always for large investor slumlords that have egregiously ignored the law (and warnings) for a long time, or Landlords that are downright evil (sexually assaulting women, physically attacking Tenants, etc.).The best protection: know and obey the law, treat your tenants honestly and fairly. 400 rentals under management, 13 years, and I've never been sued. 

Treat disabilities like you treat race, sexual orientation, sex, age, nationality, religion etc.

The registry includes everything from the example above to rape/homicide (if sexual involvement) and everything in between.2) The tenant is the mother not the son.3) Depending on 1, and if no criminal record otherwise, I don't see an issue long as rent is paid on time.Of course if your property is certain distances from schools and other places he can't live there anyway.

You can complain to your local municipality about misbehaviors.   

Northern European countries have the most open sexual education and have the lowest teenage pregnancy and rape cases in the world.

NAR also includes sexual orientation and gender identity in their Fair Housing Policy, but that only applies to Realtors and is not a 'law'.
