But this decision is the epitome of privilege. To enter a space thinking "I'm not going to think about politics" is to be someone whose sheer existence in that space isn't a political statement in and of itself. And for many, such a space is "The United States", "The Tech Community", "HN", or whatnot.
Saying "We're going to forget y'all for a week" is... just... fucking... terrible. And whoever conceived of it should be fired on the spot.
The issues will still be there to fight when you're done, just in a more appropriate forum.
If that cup of coffee is from a civet[1], for example, then it does behoove you to consider the social ramifications of your actions.
And that sandwich, depending on who you are, what you look like, and where you are, could be considered extremely political.[2]
