I think you are taking this far to personally.
The OP has quite a history of being completely reckless when it comes to 'dating' and her children.
I disagree with you on the following;
We, as parents, have a moral and legal responsibility to provide a risk free home for our children.
A rational, intelligent person that is putting their children's best interests first knows it is FAR more likely for a child to be exposed to emotional, psychological, physical and sexual abuse by bringing strangers into their homes than driving down the motorway.
Research has shown that the greatest sexual risk to children is from a mother's new boyfriend. The early 'in love' phase is known for impairing good judgement, only seeing the good and ignoring the bad.
There are two posts on here today where mothers have got into emotionally abusive relationships with new boyfriends and there have been many posts over the years from adult women that have been abused my their mother's new boyfriend/partner/husband and their mother refuses to acknowledge it, siding with the man.
There was a news story recently, 3 sisters abused by their 'step father' for many years, he being found guilty on over 80 counts but the mother still refusing to believe them and even blaming it on the daughters now deceased father.
I have not seen any smuggy evangelists on this thread, you are being offensive.
Nobody is judging your actions, the thread isn't about you.
Spare a thought for those of us that have had to go through the very real hell of child protection cases raised due to a mother's desperation to have a man at any cost, putting young children at risk with their own reckless behaviour bringing strangers into one of our child's homes and you may understand why many of us can see why the OP's behaviour and attitude is so very wrong.
The thread is not about you.
