no actually I'm gonna give this its own post.
get yourself a USB stick from any dollar store, install ubuntu with persistent storage on it. There is literally no reason not to, and it means that you now have a little computer of your very own that no one except those who physically get their hands on your USB stick can use (and you can password lock the OS) and that you can run from literally almost any PC with USB ports. Including public machines in libraries and, probably, school laptops.
If you're a kid who needs privacy, someone in trouble who just needs their own machine to play and talk to people on, somebody who doesn't have the money to get your own computer, etc etc etc, do this. Actually do this even if you do have your own computer. There is literally no reason to not have a little backup system on a thumb drive that you can use anytime. If your main computer starts acting up or gets fucked over by an update or something? Just plug in your thumb drive and use your computer from your handy-dandy mini Ubuntu installation.
EDIT: I have seen many radfems reblogging this post. I just want yall to know that op here is a nonbinary they/he lesbian and that if you touched my post you now have gross trans cooties on your blog forever and that I hope they infect and kill you. <3
