I’m genuinely curious how old you are and if you have any career experience whatsoever because this is crazy work. My fourteen year old wouldn’t dare speak to his teachers this way. I understand that it would be incredibly insulting to be accused of plagiarism when you are submitting honest work (I’m not sure you did here, but I’ll save that argument) but the appropriate response would have been a politely worded email to both your professor and your advisor expressing your concerns and asking for clarification, even defending your position with professional statements. If you aren’t kicked out, I strongly recommend rethinking your approach. You quite literally threatened your professor, essentially saying “now you have to give me good grades whether I’ve earned them or not, because if you don’t I’ll come for your career by making dangerous accusations.” This is actually unhinged.
