One slogan in the Hong Kong protests has taken on new significance: “Don’t distance yourself; don’t snitch.”

The slogan is a call for the protesters to remain united, even as different factions emerge and their tactics diverge.

During the more than 100 days of the anti-government protests, the various camps — from the most peaceful to the most confrontational — have generally avoided publicly criticizing each others’ actions. The approach has persisted despite the steady flare-ups of violence including this past weekend, when protesters threw bricks and gasoline bombs.

Carrie Lam, the Hong Kong chief executive, complained about the solidarity when she announced this month that she would withdraw the extradition legislation, which originally incited the movement.
