Not debunked, but it's all theoretical and controversial, as I say nobody really knows. Many still reasonably suggest there'd be mass extinctions from a "minor" nuclear war. Some disagree.
Basically everyone agrees there'd be some form of globally damaging fallout. Whatever the case, I'm not that eager to find out, personally.
We're not fully sure of the number, but somewhere between 3 and 20 modern day nukes will be enough to start a global winter where everyone dies anyway. If any kind of nuclear war starts out, even a teeny tiny one, most-to-all of humanity is fucked.
Real life.
Is not.
A fucking.
Trolley problem.
You are actually allowed to break the car and turn off the power.
Or more to the point, this could never have happened, because the workers wouldn't be staying there under threat of poverty.
The world is not a fucking trolley problem, there are infinite alternative options to actually stop the murder. And unless you're actively involved in organising to do so, you have no right to talk about voting to improve the system.
For sure. I agree with everything you've said here, and fully appreciate you bringing up those points. Cheating comes with a context and complex circumstances that don't make things so clear cut.
The Promised Neverland had some good dubbing. As someone who normally dislikes dubs, I think they captured the personalities well, even if the main characters are children. (Just prepare for the end of Season 2 to be disappointing).
Not mad atcha, just disagreeing. It's all good 
I do agree with this general sentiment, I've been in a cursed, abusive relationship and cheated on them (though not to the point of sex) because at the time I was being quite explicitly threatened and coerced into staying in that relationship. If I had been found out, it would not have looked pretty; OTOH cheating like that was a major step in giving me the confidence to leave.
I have no idea what the woman's circumstances were, but I agree they could've been very complicated and not as black/white as it seems.
At the same time, I also don't think it's fair to claim her lies didn't hurt the OP, and I don't think OP is a bad person. I wouldn't have blamed the other person if it had happened in my circumstances. I can 100% understand why a person might cheat (obviously, as I've done it), but if you betray a person's trust, especially the one who actually hasn't wronged you at all, then it's not unfair or unreasonable for them to react negatively, nor to assume the other person should find out too.
Personally, I'd do the same as you. But it is an understandably murky moral sea, and I'm not sure any answers are 100% right. Not confronting it there and then could mean OP just gets lied to more.
While I do agree they can, in a small way, help create that idea. There are multiple western voting systems where even undeniably winning the popular vote does not win or lead to mass discontent for failing to be governed by the actually mandated parties. If people aren't even reacting to that, winning a lot of votes is never going to mean that much.
Does dissuading fascists from voting actually help? The more important part is convincing proles that voting is immaterial and they need to do other stuff to effect change. Whoever and however anyone votes, fascists will get into power.
