The intention of the text is quite clear. It looks down upon people opposing immigration. The arguments from top-to-bottom and from bottom-to-top are quite different in tone.
IMHO there is nothing "fortunate" about dragging politics into programming, regardless of your or mine views.
I would find it fortunate and valuable if at least certain human activites stayed out of political culture wars entirely. If, instead of "my side, your side", there simply wasn't any need to think of a side for a moment.
I already deleted my FB and TW account to get rid of incessant political flamewars and I feel aghast that they are now following me to Python release notes of all places.
I’ve always considered the no-politics at work rule to be a neutral zone in an armistice. It’s been in effect for so long people have forgotten why it existed and see nothing wrong with resuming agitations. The ‘politics is personal’ and ‘bring your whole self to work’ shift is an intentional reinsertion of politics back into work and like the Chesterton’s fence parable I think we’ll rediscover why that rule was there in the first place.
The people advocating for bringing politics to work forget that people with opposing views will also do the same, and then you end up with a hostile, polarized and distracting work environment.
