Yeah ... I mean if it was their favorite movie or book, I probably would do something like that, but particularly when it's a movie I don't want to see because of X, or one that I saw and hated (sooo many versions of this with The Help), coming up with a good lead-in can be tricky. Plus that feels uncomfortable too, if I'm reaching too hard - it feels like internally condescending, like I'm treating them like a child or something...

Although if the people in question have already voiced the thought that you're just a humorless feminist SJW buzzkill, then some dumbing-down is probably necessary. But with someone who hasn't done that and is pro-SJW but just not as educated, I feel bad if I assume bad faith.
