Most of us were raised the same way and would have agreed with her as kids or even recently. Views on the topic have changed but not for everyone.
My Dad was a sohisticated man, my mother kind of country. In middle age they had some financial and health reverses, and bought a big house cut up into small flats, except the ground floor which was a large apartment. We moved into this large flat when I was 15, and my 3 sibs down to 4, in the mid 50s
My mother was always in a dither because her tenants were, she believed, behaving immorally.(Ie bringing dates home for some naked fun.)
Like many attactive older city neighborhoods, this one drew lots of gay men. My Dad solved his problem of a nutty wife possibly messing up his business by only making new rentals to gays and lesbians. My Mom was ecstatic, because no one was any longer bringing home housemates of the opposite sex. My brother and I thought it was hysterical, both because we liked the elegant solution, and because we wondered if my Mom ever wondered where all the guys with orange hair and stuff came from.
The only time I ever experienced gay negative culture was college. But the rest of my life as far as I knew there were always lots of gays around, and they were as accepted as anyone else. Gay men seemed like anyone else, but better dressers and more polite.
I knew a number of lesbians also, as my wife was in a social group that contained many lesbians, and she set me up as a handyman for some of their household jobs. It was quite comfortable, they always gave me coffee, paid me well and unlike some heterosexual neighbors were totally uninterested in flirting with me, which made everything easier as my wife never liked me to be around women that she thought were looking for some sport.
