Illegally immigrating and then seeking asylum afterwards is still illegal immigration
Asylum is legally considered part of the removal process for illegal immigrants. Assuming this occurs before they're caught, why would you kick them out when they're following the process?
that's violating your visa is illegal, it's no where near as prevalent as illegal border crossings

FOSS has a lot of leftwing advocates because it distributes the means of (software) production. The initial idea was inspired by Communism. Lemmy has a lot of FOSS people in the tech communities so you see the spillover there. You're possibly more used to seeing the Silicon Valley type of tech people who are right wing if not anarchnocapitalists.
