    At the speed cars move at, air behaves much like water. They’re both fluids. The faster you move the more resistance it has, but also the more dense the fluid is the more resistance it has. Moving quickly through the air is similar to moving slowly through water.


  • They addressed the elephant issue in their comment. I recommend you read it again. The summary is elephants evolved without predation, so they don’t bread in large numbers. Prey animals breed with the assumption a not-insignificant portion of their population will die prematurely due to predation. If this doesn’t happen then their population balloons until it consumes all available resources, then it collapses.

    This happens fairly frequently where we’ve removed predators from the ecosystem. Its why we promote deer hunting, for example. We’ve removed their natural predators, and if they aren’t culled then they will grow until they collapse. This is well understood and not controversial.

    I guess we could engineer the planet until this isn’t an issue, but that’ll take a few millenia and probably isn’t the best idea. Let nature be natural. It’d be fascist to assume it’s our domain to conquer and dominate into submission.

    I don’t know if it’s rare or incredibly hard to document. How do you attempt to track that? You’d need cameras in the water all over the place, all with an internet connection, and the water would have to be clear enough to see through, and the attack would have to happen right next to the camera, and someone would have to notice it.

    I guess the alternative is we put a tracker in a bunch of moose and then dissect a lot of orcas and try to find the trackers.

    It just seems like something we’re unlikely to know how common it is for a very long time, if ever.







  • I was in college and living with a bisexual Saudi friend at the time. I’m a straight white man, so I wasn’t a target, but he absolutely was. I sat with him in the kitchen while we got drunk and he cried.

    The good news is he made it through fine and I think is doing well today still in the US. It’s going to suck, but most of us are probably going to survive this. Don’t give up all hope. Build your community, organize, join mutual aid groups, and build what we need to take back power in the future.

    They’re going to try to take us backward, but make them take us kicking and screaming. Don’t give up and let them have it for free.


  • It’s absolutely a belief and it used to be true. For millennials especially it was true. We grew up with technology around us, but they required effort from the user to make them work. These created a lot of self-learned resourceful technologically literate people.

    Modern technology almost all wants to prevent you from messing with them. They function out of the box and limit your ability to modify them. This has created a lot of people who can’t understand how technology works beyond the user interface. They’re great at using a touch-screen, but they don’t understand what the device is doing beyond that.

    Just to be forward, I’m not trans.

    This election isn’t the end. Civilians probably aren’t going to come after you or anything. You quite possibly will lose access to some forms of Healthcare you are allowed to enjoy now, which is pretty fucked up. You’ll also likely be discriminated against in government paperwork, like having to put your birth sex on your drivers license and that sort of thing.

    In the end, you’ll probably live. Keep your friends and community close and work to make things as good for each other as you can. Find alternative forms of Healthcare if you need to and can. Keep some hope alive that we can come out of this stronger and more united and turn the tables in two years, or at most four. Don’t give up. Don’t let them just have a victory. Join local mutual aid groups and whatever else you can do. Keep fighting.

    Remember, as bad as this is, this isn’t the first time trans people have been discriminated against. Remember those who came before you and fought to improve things to get to the not perfect but livable status-quo we temporarily had. Don’t take it for granted. We can get back to that point again and further.
