OP could have made this point in a better way without expressing it in a way that isn't true or implying that nationality is by birth. Let's do that having looked at https://www.bfs.admin.ch/bfs/en/home/statistics/population/m...

  * 41% of the permanent resident population aged 15 and over has a migration background
  * 27% of the permanent resident population is not Swiss
  * 22% of the permanent resident population was born outside of Switzerland

Notice the subtle distinction in the phrasing of the second point above and OP's phrasing? OP chose to phrase in a way that was a) wrong, and b) misleading. This has been classic tactics around this vote and others over the years.

Here's some more countries by immigrant background: https://en.wikipedia.org/wiki/List_of_sovereign_states_by_im... # Switzerland is on a par with Austria, Australia, and New Zealand, and way below many other countries that have > 50%.
