After reading the replies I do agree that completely removing the feature or at least abductions isn't the answer, I do believe the pregnancy feature should be either optional though or toggled (after all you have to try for a baby to get a baby and not based on a 1 to 4 chance) as should a more direct toggle to enable or disable abductions.
I understand they are part of the lore of the Sims, I love the x-files myself but when I sit down to watch it I know what I'm in for. Honestly it takes a lot to trigger me and I suspect the reason it did this time was because it happened to me in-game and so very randomly I felt I had no control over it and wasted so much time reloading saves to find a point before the abduction. originally I just went with it until I discovered he was pregnant and that combination really bothered me.
As for abductions themselves maybe more gameplay should be added to them to give them more depth than a rabbit hole abduction resulting in pregnancy, like waking up on a alien ship your sim can explore and make friends on. At least your sim is still some form of control.
It also sounds like a hard toggle switch could also work good for people who want to be abducted and struggling to have it happen, where in a toggle on would not only allow it but also increase chances.
I agree that nerfing a game to make it as non-offensive as possible is not the solution too, but a good game designer knows the difference between giving players control and forcing situations on them. That doesn't mean those situations can't be present in a game but rather how you let a player interact with them is left to them to decide.
Again, giving players choice.
