Do you want to manage participatory spaces?
The Debates component provides a basic participatory space to organise debates around a topic and have people comment on it, express their position: agree, neutral or against. Participants in a debate receive email notifications when somone mentions them or replies to them (dependent on their notification settings). It can also be used to present a given manifesto, proposal or other text and allow people to endorse it.
An important decision is whether you want to allow all participants to be able to create new debates or only leave that to admins.
Note that participants can also organise themselves into Collectives and express their collective position in the debate.
