My DS has two streaming devices (that I know of) in his room, one being a desktop and the other his phone.
I have always kept a loose eye on the desktop and what he is accessing, as he never logs out of YouTube or daily motion. Most of the time he is watching Japanese animation or music videos, this last two months though he has been watching 'red pill' videos. He appears to have focused on a channel called entrepreneurs in cars for a few weeks, binged on that and then spread, watching in evenings mainly.
He never espouses any odd views, doesn't even seem to comment that much although he has left the odd thumbs up. I don't feel I have enough to challenge him, but at the same time I don't want him delving further into this. Ideas? Don't like snooping but its the only way at the mo
