I wasn't previously aware of that incident in Malaysian history, that's horrible.
It made me think of what happened in Indonesia just a few years earlier. https://en.wikipedia.org/wiki/Indonesian_mass_killings_of_1965%E2%80%9366
The documentary The Act Of Killing is a surreal look into it, and where Indonesian society and the perpetrators live with it today.
Oh my goodness, I never heard of this incident having happened in Indonesia, even though we're just neighbours. It's terrible, and far more severe in how much bloodshed it created in its wake! I'll definitely need to take a look at that documentary, and now more than ever it's a pertinent subject to discuss.
It's truly sad to see these things happening, and that after everything humankind has accomplished in its history, there's still one thing we've not yet been able to do - love each other. Always, there's some hatred for one another, and it leads to acts of violence like this. It's such a shame, and I do hope these protests can serve as a wake up call. I'm only afraid that we'll have to do more damage in the meantime, and that eventually everyone will just forget about it.
