Changes in mores

I read quite a bit and lately I have come across so many gay characters in various situations. They have have now move to a mainstream part of society and it is politically incorrect to make negative remarks about them. My, how times have changed. Same sex marriages, once in the realm of speculative fiction is now a reality in many states in the United States and various countries around the world. I don't know if this will continue or if there will eventually be a backlash.

    As far as changes in society, there has been a redefinition of what a family means. Single parent, with a child being raised by his mother (or father),multi generational families(mainly immigrants),gay parents and more. No more nuclear families in the majority, at least in the U.S..
