[No, if 5 men & 7 women live together in a group marriage, an owner shouldn't be forced in a Free Republic to rent to them...a passage in the Bible (1 Timothy) talks about not participating in the sins of others...and landlords shouldn't be forced in this way...this goes beyond homosexuals because the issue is the same for cohabitating heterosexual couples]
And, BTW, these laws go beyond where you live to where you work. Companies with 15 & over employees have to abide by them -- including a law that will allow cross-dressers & gender-benders freedom to dress as they will in the workplace. Imagine being a retailer forced to have employees cross-dress and such men using the women's bathroom in the workplace.
You are confusing PUBLIC with PRIVATE.
What you do in your home, is private. You can exclude anyone you want, for any reason; or no reason at all. You may opt to not even answer the door for any person, at any time, without warning, without excuse and without cause.
When you run a business, be it a resturant, apartment, or service based company - you are now part of the PUBLIC domain. Now the laws that govern the public, govern you.
If you apartment accomodates 12 people, and the fire-marshal has signed off on 12 people living there - who lives there is NOT your business. All that you are ‘legally’ entitled to worry about is the upkeep of your property, and that you are paid your rent on the date promised. If it’s 5 men and 7 women - that is not your business. If you rent a hotel, you may not demand to see a marriage certificate before renting a room to a man and a women; as their sex life is none of your business.
The fear of having to hire cross-dressing employees is over-stated. If I run a store, part of the job description is that my employees must present an image that is in line with my business goals. If I run an upscale retail store (Dillards, Macy’s, Foleys, ect) I have every right to demand that my employees are clean, their hair is cut to a presribed length, and that they dress in accordance to the image I wish present to my customer base. For this reason, you will not likely encounter a cross-dressing degenerate working in the women’s section. No manager would tolerate this; and for good cause. By the same token, you will not see a hippy wearing Birkenstocks and Osh-Kosh B’gosh overalls working in the suit department.
Now, if I am running a factory; where the public does not see my employees, then there are different sets of expectations and behaviors that come to bear.
