Well my point is that positive, doesn't actually mean positive - there could be more meetups about coffee because there are less good coffee places to consume it. To illustrate this point: I would intuitively expect there to be more pro life meetups in a liberal area and more pro choice in a conservative one - since the norm is baked into society and people don't feel the need to meet up about what everyone agrees to. A much better approach would be to use existence of business that support said aspect of a city.
