I'm taking away all of my children's social media privileges?

This week, I've allowed my twelve-year-old daughter to own an Instagram account, given that we know what she does on it at all times. I, as well, decided to give social media a try (or mamapedia), and feel that I am being made fun of by the other moms on this website. You all have taught me that social media is not a thing that I should expose my children to. Thank you all for your time and your "advice", but I felt much better off without it. I come from and extremely Christian background and I feel that I am being disrespected for it. I hope you all live wonderful lives and end up in Heaven one day... Praise Jesus!
