Backstory:
A few years ago my mum started believing in conspiracy theories, went from pretty open minded to racist and started sharing populist thoughts basically saying stuff like "there's a NWO organisation, Merkel is the granddaughter of Hitler, the white population is being infiltrated by non-whites and its being replaced by those filthy immigrants" etc. etc.
This of course caused many arguments and disparities between her and the rest of the family since we all tend to be open minded and think that these kinds of thoughts are just complete and utter bullshit.

Now onto the main part:
A few months ago after my mum got diagnosed with cancer and after my stepdad at that time left her she started dating this guy who's sharing these thoughts as well if not even a tad bit more extreme. For example I know that he's a flat earther and doesn't like the way our system works, especially the school system since the kids are being "indoctrinated the wrong thoughts and are being teached unnecessary shit".

I'm 19, my sister is 15 and has never been particularly good in school. My mum decided to take her out of school and to "homeschool her at the school of life" when she's ready, which is btw illegal since it's the parents responsibility to ensure the kids get the education and send them to school. 
My mum obviously doesn't want to have any of that "indoctrination" in state schools being pressed into her kids head, that's why she took her out. 
We argued a lot about this decision since I suspect that my sister will just use the time outside school to not do anything and therefore loosing contact to how the real life is, not getting a degree and not being able to not make anything out of herself. 

I and others from my family also fear that she'll try teaching my sister things that are coming from her reality. Things like those mentioned above, that the holocaust wasn't real and the allies faked it and that the talk about climate change is a huge scam caused by idk who.

I'm having thoughts of reporting my sisters absence and my worries to authorities which would mean that my sis would be forced to go to school and I'd probably be dead for my mother since I betrayed her.


So WIBTA if I reported her to the authorities for neglecting my sisters education and probably destroying her future?
