You do understand that there are parents who would make their children homeless (or worse) over issues of sexuality and gender right?
Is it that important to be able to snoop on every facet of your child's life that you support turning what should've been a safespace for children who find themselves in the above scenario into yet another place they're forced to hide.
Also, if you're at the point where you're resorting to using the law to force secrets out of your children, rather than having them trust you enough to just tell you, you should probably question your relationship with your children.
