That's a very sweeping statement. The fact is it can be much safER if you are armed with knowledge, and no matter how much we want to keep our kids off the internet, we live in an online world these days, and unless we lock them in a box at some point, they will come into contact with it.
Whether that is at school, home, friend's house etc etc so I think as parents it's our duty to be fully aware of the dangers yes but also aware of how we should educate our kids to deal with things should they need to.
And as you believe social media is not safe, then you are the perfect person to listen to the episode and understand how to help your kids, or parents you know to ensure they have the knowledge they need for their futures.
I'm sorry the name of the podcast offends you, but the content of it is actually very helpful and doesn't for one minute suggest that children should be on social at an early age etc. Take a listen and then feed back.
