this is a pretty paranoid view. the restrictions only apply to very specific categories where there have been laws against discrimination for many decades. perfume and razors are not among them.
Specific categories such as employment and housing, for example? Urgh, fine, pretend my examples were about bachelor pads. Same deal: don't target the young men who actually buy them, because we don't like those people and we don't want any part of the economy to cater for them.
The people pushing aren't doing it because they're against any types of tenants either. They want all types of tenants to be able to get housing and take advantage of things that make it easier.
