One of the best parts of texting is getting to keep receipts on exactly what someone has said to you. If you are talking to someone on the phone, you might not have the foresight to record your conversations before something comes up that is worth documenting (That, or you live in a state where it's illegal to record a conversation without first getting both participants consent.). But with texting, you're more likely to passively keep messages on your phone whether you think they're noteworthy or not. You can screenshot a text message and ruin somebody's life if you so choose, but if your friend calls you a name over the phone, it's your word against theirs. Of course, text screenshots can be fabricated, but the truth always comes out in the wash. These parenting texts might be anonymous to you, but for the strangers who posted them, they are bold pieces of evidence supporting the theory that their parents are insane.
