lactivist 

"A lactivist is a lactation activist: someone who considers him/herself an advocate for breastfeeding, whether or not s/he's nursed. Lactivism comes in many forms: choosing to breastfeed, choosing to breastfeed for an extended period of time, choosing to breastfeed in public, choosing to smile at a breastfeeding woman, encouraging other women to breastfeed, educating the public on the benefits of breastfeeding, lobbying for pro-breastfeeding legislation, etc. Maybe you're already a lactivist, and didn't know it."

from A Call to Arms and Breasts by Stacey Greenberg

She and her friend are both lactivists.

"Breastmilk is best for all babies" said Susie, a lactivist from Central City.

lactivist 

A erson whom claims to be an activist on a cause but it's just empty words, as in lacking any enthusiasm, also known as an Armchair Activist.

He went on about the green issue but campaigned nothing, he's such a lactivist

ambulance chaser activists 

A left wing (BLM/Antifa) activist who jumps on to any officer involved shooting when there is little to no information available to make far reaching politically motivated assumptions and demands. Eventually these assumptions are overwhelmingly proven false by bodycam and autopsy reports

I saw the bodycam after hearing how she 'promoted peace' only to see her trying to stab someone. You just can't trust those ambulance chaser activists

Person 3:”Now that you think of it, after July n stopped posting about it. n probably is”
