[a character sits at their desk, in front of their computers, and complains angrily]
Mainstream media? Unreliable, biased, full of fake news, they keep lying…
You can't trust them!
[changing to a point of view beind the character allows us to see that their screen is filled with other angry characters that look like the main character]
That's why I get all my news from angry dudes on social media and men's right activism podcasts
Uh... Take away the ironic "men's rights" part and you are your dad. Unless you're actively ensuring your feeds are not algorithm content and the parts of the internet you're hanging out in aren't socially reinforcing...
Otherwise, we call these "echo chambers". And funny enough is that those in them create the most "me vs them" content, all the while constantly reassuring "the audienice" that they're not in one.
But, yeah. I'm sure I'm wrong and helping your dad to navigate through the ongoing onslaught of media is something you've tried.
Edit: GOD DAMN I'm so self- righteous and sassy tonight. Ignore the sass. Get the vibe. A apologise for the sass, but I won't delete because the vibe.
Point is, you and your dad have two opposing feeds. Recognise that they are feeds and move on from that.
I'n not the person you replied to, but I just want to offer kudos for your edit. Recognising that you didn't need the snark is a rare thing online now-a-days.
