To be fair, if a person in an apartment building is using unretarded materials, he is putting many innocent people at risk in case of a fire.
Plus, your disease thing doesn't have to do with genders.
Why, if their materials are fire retardant? (We're talking about pajamas and linnens, not building construction).
G.R.I.D. (now known as "AIDS" because Gay Related Immune Deficiency was somehow not politically correct enough) damned sure does have a lot to do with homosexuality, and initially was gender specific.
It has been spread to non-homosexuals by 'switch-hitters' and 'anything goes' people, IV drug users, contaminated blood/products, even poorly sterilized surgical equipment, but like the old joke, it got to San Francisco in the back of a Hudson, and at one time it was confined to the homosexual (male) population.
Now, of course, with Obamacare, those of us who can no longer afford health insurance get to buy it for those 1.3 million HIV/AIDS patients who will cost a trillion dollars for medical care in their lifetime (and that does not include the ones they will infect).
