Please carry on lecturing a coeliac about the risks associated with food allergies. It's not patronising in the least.
The answer is that I have to eat, and sometimes that involves a risk of cross-contact. The alternative is literal fainting.
Re the nurse, the alternative to trusting the nurse is that the child or I stay ill, get iller, or die.
Re trusting a child with random women, most people don't. That's why DBS checks exist. DBS-checked women are still safer than DBS-checked men are. It's also why safeguarding protocols about not having staff alone with children exist in some settings. And again, the tiny risk is worth the trade-off of having the child socialising with peers.
It's not the women of any given ethnicity that do the cat-calling and grooming and raping, but the men. White men groom too, like Epstein, they are just more subtle about it than the Rotherham gangs were.
I remind you that 6% of men are rapists and they are usually repeat offenders. These 6% of men perpetrate over 95% of sexual assaults and 100% of rapes. Only 5% of sexual assaults are committed by women. A man is literally 19 times more likely to sexually assault you than a woman is, and infinitely more likely to rape you than a woman is. No woman can force me to become pregnant, but a man can. 80% of rape victims know their attacker before the rape and 50% are raped by current or former partners (and yes, #metoo). By not dating men, a woman lowers her risk of being raped by 50%. By removing men from her social circle as much as possible and making sure to never be alone around her friends' husbands, she lowers that risk further.
I don't starve by not dating men. I don't get ill from not dating men; if anything, I am healthier because sex with men gives me cystitis. No child is deprived of an education or socialisation by its mother not dating men, to the contrary, the child is safer at home if there is no unrelated men around. I don't lose out by keeping away from men, and I gain real safety from another sexual assault by keeping away from men.
You keep asking about femicide risk over and over, and I think it's because you don't want to talk about rape. Rape is far more common than the murder of women is and, by definition, is something only a man can do. And the victim has to live with the consequences for life.
