There are always protestors there. The topic may change or there may be several groups there at once. Just prepare to walk by them confidently and not engage. Even if you agree, it's not worth it. Beeline into the park. When we were there last, Dec 2023, there were religious groups, political groups, anti war groups and a union. Some were shouting lude things and had inappropriate signs we didn't want our then 9 yr old asking us about. It's life. Sometimes those things happen in our own city intersection. I am now prepared to answer at any time "mommy, why are they holding up a uterus?" (and that wasn't the inappropriate one) or other questions that aren't usually discussed on vacation. NYC was worse. at 10 yrs old she was actually scared in Times Square. Honestly, public demonstrations are a freedom we take for granted. I try not to let them bother me because if someday we can't that would be terrible.
