Today is an extremely reactionary holiday. You probably will not even be listening to the radio without hearing some off the wall propaganda about the US being the best country or some other nonsense. Besides American flags everywhere you look, and not a single one is on fire. It is a good day for isolation and meditation to avoid the insane amount of propaganda that is going on outside.
It is very difficult to talk about the people you will see if you need to go out today for groceries or work, but know that many cult recruiters and political extremists have a license to fly their flag today without repercussions. Whether it makes you offended or alienated, today is not a day to leave home at all if you can avoid it.
It is safe to spend the day binging Netflix, on the computer, or even meditating. This is not a day to celebrate anything as far as I know, but there are a lot of other things you can do.
