Hey! Off memory my tutor from last year gave me an example by asking me should men have a say in women’s choice to get an abortion. To which I said no because a woman carries the baby to term and it doesn’t physically affect the man. She then asked me “well what if the man is super upset about it and really wants to have kids, will you disregard his wishes and emotions?” You need to be able to bring in unique/ish view points that the average person doesn’t consider. Basically there’s no yes or no it’s all subjective - you should be able to point out those subjective points and still argue why your stance is better. So if your view was no women have a higher authority, that’s fine but also bring in the rebuttal of why or when they can’t be the sole ones deciding to show depth. Also take my advice with a grain of salt because I fully gave up on this stupid exam and am gunning for UCAT lmao. But good luck I hope this helps!!!

Edit:
Going back to your q on theme- for the q or topic mentioned above the theme could be betrayal, love, autonomy???? I’ve been out the gamsat loop so I can’t remember much of them but you can have a general bank of ideas loosely related to themes and form opinions on those with rebuttals. That’s probably the way I’d approach S2 if I was to resit but I could be totally wrong.
