I have a hard time watching it in a movie

So it would be fair to say I would have no problem taking a shotgun to the guys raping the woman or man being raped!
I watched the movie "I spit on your grave" and I'm not ashamed to say I was physically sick. I had to stop watching it. I have a close girlfriend that was raped 3 years ago (by 3 guys) and she's still a mess and scared of people. Maybe that's why I'm so sensitive to it. I saw her in the hospital hours after the rape...I'll never forget that look in her eyes. So for someone to stand by and watch it's horrible!
