Many people have expressed this concern and it does make sense i.m.o. Other people have said that, to be disruptive, a protest taking place when lawmakers are in their offices is a good idea … so they will experience the protest first hand. (a little like what happened during the January 6th insurrection i should try to find a better example)
Some people will not be able to attend but this might be just one group of (50) protests in an escalation of many more …
