> or is this supposed to mean that they created various groups and the total count of all the members is 32 lakh?
I am sure he meant this. But I am more interested in translating what he said verbatim than add/remove meaning from it. What you interpret it as is up to you. But a translator should be true to what the source said and not add/remove from that.
But to actually give more context to the video itself: Amit Shah (the speaker in the video) says that one of the members in the group sent a fake message saying that a local political opponent slapped his father (who is also a politician and an erstwhile Chief Minister). That message spread like wildfire. And many people of that State (where the election was taking place) did not take kindly to that bit of story (slapping your father is the worst thing you can do in an Indian context). So Amit Shah says that even though that message worked to the ruling party's advantage, that should never have been done. He told them (the workers of the party present in the gathering) to not indulge in such activities and instead spread the truth. After that he makes that statement that the message was spread so fast only because they have a group of 32 lakh volunteers/party workers in it who spread the message. Now obviously one group cannot have 32 lakh members. Neither is Amit Shah so tech savvy that he will moderate/admin the groups. I am sure he doesn't even know/have the time to create a WhatsApp group. There is an IT wing that manages the show. So when he says 32 lakh members in a group, you should interpret it as many groups but total count of 32 lakh. Now it definitely isn't 32 lakh groups (that would be crazy and pointless).
So only when you take the entire speech into account will you understand the context in which this was said. But if you cherry pick, you can derive any meaning you like.
