It's a real shame, but all political and social movements, at some point, break up into factions. The factions debate their relative necessity, claim authority over areas of discourse and action, and generally vie for power. They stop coordinating and communicating with each other. There are occasional acts of sabotage. The competition of the market economy (including the grant-funded non-profit sector) and the expanse of human vanity demand this distinction. Everyone needs to find their niche. An ecologist understands this as well as an economist, an activist as well as a lobbyist, a rabbi as well as a lawyer.
