I posted on the USA BC why a CO person shouldn't be allowed around The children and this is one of the best responses.
Once any of us have either, reached the age of 18 AND moved out, OR had children and became heads of households of our own, or BOTH, we are all adults. So....
As adults, we get to have our own way, in our own lives, as long as we don't harm others. Which means: we get to determine who we keep in our lives, and who we don't HAVE to talk to anymore.
So if a person has warranted CO from somebody, that means the person who made that choice to rid themselves of "you," has every reason to do so. Whether it's because you are BSC or because you wear an inordinate amount of neon green - it doesn't matter. Because the person from whom you are CO chose to CO you.
Now, Minor children are inherently a package-deal with their guardian(s). If an adult with children CO you - then you are automatically CO from their kids. Should have thought of that before you filled your closet with neon-green.
As the CO party - YOU do not get a say in the choices of the party that CO you. So whining about why doesn't matter. If you want access to the children, you need to repair the damage with the adult. If that means filming your bonfire of neon-green clothing and emailing them the video, then you suck it up and do it. Or you gracefully accept that you don't get to make contact with the children.
There is no negotiation, and it seems that the thread you are following has CO parties in it who appear to presume they have a say. They don't.
