They step back on that when the problem is turned around into "why does your house have walls? why do you have locks and doors?". It's not because you have something to hide, it's because of privacy and safety. And we need these spaces to provide us with a modicum of safety and privacy because some discussions can only emerge in those spaces, some ideas need to be discussed in those safe spaces and because I wouldn't want that the world in which modern children grow up in has entirely given up their right to privacy. We always end up using the bad as something that needs to be guarded against, but we seem to fail to see all the positive experiences that have emerged in those safe private spaces as we were growing up...
Hope you are better now and thank you for the write up!
