My position is that we need not necessarily participate in anti-war initiatives organized by reactionaries, but we also should not oppose or denounce said initiatives (of course in all other contexts we should continue to ruthlessly criticize and fight against those reactionaries!) since that does not benefit us in any way. We should build and organize our own anti-war front just as Lenin advocated for communists to build their own party and not join bourgeois ones. Communists must not allow themselves to be subsumed into either liberal or reactionary politics, we must remain separate and advance our own revolutionary and unapologetically proletarian, class conscious views and agenda because no other groups will. Occasionally we can work with non-communist groups on an issue by issue basis but that is purely tactical.
