Off the top of my head, I can think of two solutions - one obvious one, and one you probably won’t like.
-
Use due process to find and prosecute the people who are here illegally.
-
Get rid of the laws that make it illegal for people to stay here.
The system as it was before Trump was certainly favorable to the concentration camp solution we’re using now, so yeah, I think going back to that would be a good start. After that, we can continue improving to one of the other solutions I suggested (or maybe even a third one I didn’t pull out of my ass).
That analogy doesn’t really apply though. The decision to change master to main was a collective one, not made by “some corporate board room 1000 miles away”. It may feel like that’s how it went down because you only noticed when GitHub changed their defaults or whatever, but that decision was not made in a vacuum, it was the result of lots of people saying “hey, this is a problem, let’s fix it” for a long time before any actions were taken.
