To be fair, I feel like there's a lot of videos that would traumatize you if you watched them, not just ones related to meat. Sure there's traumatizing videos you should watch, but actively seeking that stuff out seems like no way to live.
I feel like many have detached themselves way too much to what the realities of life are. We should be watching people and animals die because we are now so sheltered from things that we were born into as a species, that every animal other than us experience we have become sensitized to it. Trauma and violence are part of being a living being and I think it has distorted our perspective and appreciation for living. You won't see many people who deal with daily violence commit suicide because they're in survival mode which should be the norm for anything that is living. It changes your baseline for thise experiences. Lows might be very low but tolerable and highs will be extreme because something as mundane as a day without having to chase down a deer and almost get killed by a lion is going to be the most exhilarating day of your life.
Veganism is the result of our easy low risk existence and it makes us less adventurous and a lot less likely to make it into space. Space vegans will never be a thing.
If I was actively funding the abhorrent things in those videos, you'd be well within your right to tell me to stop, or at the very least insist I watch them.
