ELI5: why are people upset over red starbucks cup?
gpt
It's part of a larger "War on Christmas" argument that get's brought up every year.  Over the last several years, companies have done different things to make the holiday season more inclusive for everyone.  The big one was getting workers to say "Happy Holidays" to customers instead of "Merry Christmas" since not everyone celebrates Christmas.  This pissed a lot of people off who viewed this change as trying to get rid of Christmas.  The red Starbucks cup is seen as another example of that.  Usually, Starbucks changes their white cups to red around this time of year and it usually has some sort of wintery or Christmasy design on it.  This year, it's just solid red and Starbucks has been accused of taking Christmas off of their cups.
