Goosefoot we all have our different limits, and while rape isn't necessarily a complete no-go area for me, I do think it has to be handled more carefully than such things as war and non-sexual violence - simply because it isn't anything like a fictional concept for a lot of women. As an example, Theon being tortured over the course of a whole season was deeply unpleasant to watch but it's hardly likely to reflect the direct experience of any viewer and thereby trigger a PTSD response. Whereas about one fifth of all female viewers will have been subjected to sexual violence in their own lives and will probably not appreciate having glossily-produced rape scenes sprung on them - like what happens to Daenerys on her wedding night in the very first episode. It wasn't even a rape scene in the book, so what was the purpose in making it into one for the show, if not to hammer home the Dany-as-victim narrative and make it even more problematic when she has to basically learn how to be good in bed to stop Drogo from raping her?
The changes to that scene were strange and ineffective, though I suspect they were at least partly attempting to avoid the criticism of minimising forced marriages. As became apparent, the producers were rather lacking in terms of their own storytelling skills or psychological insight and often when they made changes, even justified ones, they didn't really seem to consider the knock-on effects to character development or the plot more generally.
I don't entirely agree with you that many people haven't experienced the other kinds of violence that the show depicts, I think experiences of living in a war zone or other very violent situation aren't nearly as unusual as people imagine. Probably not one in five, but I'm not convinced the number itself matters that much, if some people are impacted they are impacted. But quite a lot of women don't find the sexual violence on GoT upsetting in that way - viewing stats suggest that fans are only slightly less likely to be women which seems to suggest to me that it doesn't make it seriously less appealing to women.
Some people just will not want to watch certain types of material - my husband had to clean up quite a number of torture victims at one point in his career, and as a result doesn't much like to watch, or even read, anything involving that kind of violence. But usually it's not a complete surprise when you find it in films, if you don't want to see that sort of thing.
I was much more unhappy about the way they dealt with "consensual" nudity, prostitution to some extent, and also just trying to push the envelope in terms of showing off parts of people's bodies.
