As somebody who has been used as a prop when I was a kid or in retrospect to when I was a kid I very much agree. People who use children as props for these types of arguments are disgusting and despicable people, it is incredibly dehumanizing and demeaning to use somebody who can’t stand up for themselves as a prop to win your own stupid argument.
It’s never the kid’s fault in it though, you shouldn’t blame them personally, the people who claim to be helping them are actually hurting them by attempting to use them to further a narrative.
