I'm half Mexican half Finnish. Strange mix. Pure white.
I understand the hardship
Random people do not think my father is my father.
I've been stopped multiple times by police walking with him to make sure I was okay when I was a kid. All good, just walking around the neighborhood with my dad lol.
Edit: It's also funny growing up people asking me who our gardener was. Also my dad.

Some form of torture. The thing about torture is you can always add "and then..."
Psychological and physical
Imagine being forced to rip off your significant other's fingernail.
And you might say "There's no way I'd do that"
Sadly you will. Either to save yourself or them from more torture.
You will do it, we all would. That's scary.
