If you get overwhelmed with stimulus in general headphones - maybe just in one ear - that don’t block outside noise but can play something familiar might help.
Just gives you something to focus on that IS comfortable when other aspects might not be. Music or meditation or podcast or whatever is familiar reassuring. Also battery backup.
I am interested in protest but not in violence so made a cloth sash that says “peaceful protest” on one side and “nonviolence” on the other. Just to help keep myself identifiable as someone who is not looking for a fight.
So it’s important that people who are elderly or have young children feel safe.
If you want to get in conflict with police please do that at a different event that is intended to be disruptive. Please let the peaceful protest be a place where everyone is welcomed and we can attract huge numbers of law abiding citizens.
100% civil disobedience will be needed. This is not the day for that. This is a “big tent” day. There will be plenty of opportunities to cause trouble- but if you cause trouble at this one - that I am attending with my 87 year old father - he will never come with me to another event.
So please don’t. Please disrupt a different event.
