You need to look for information. There are Jewish Coalitions out there fighting against this Genocide every day.
When Pro-Palestinian people get arrested, these same Jewish Coalitions are out there supporting them. They are out supporting these actions. They are involved in these actions.
For that their Cost of Solidarity is quite high. It's relationships with loved ones and their communities. It's constant harassment from Christian Zionists.
When you see them advocating, support them.
