It seems you didn't quite understand me. My bad, i should have formulated it in a better way. Let me reformulate it again:
How can i acknowledge something i don't have any idea it exists?
We weren't able to acknowledge Australia's rape culture, because we didn't know it was a Problem.
You can't expect me to have acknowledged it previously, when this is the first time I've ever heard about it
If you think that, then maybe it's time to take a step back and think about how and why you got to that conclusion.
