Let me show you two videos. They both are about activism against the Israeli occupation of Palestine.
This first is documentation of an action by BDS activists against a promotion of Israeli technology at the Boston Museum of Science. They picket outside the museum, & then the group infiltrates the audience at a presentation (becoming half of that audience.) They keep interrupting the presentation, & keep getting booed by the others in the audience, except for one man who says they should speak their mind for five minutes & then let the presentation proceed. All the activists are escorted out one by one by security after standing up.
