Any person of any ideology who actively promulgates something as True or Natural in an inflated or empty way; someone who bloviates without substance or measurable fact. A mashup of “Harangue” and “Orangutan.”
Groups are communities of people with similar interests or lifestyles in common. Browse around! Some are private so they require acceptance by the moderator - but those are just to make sure, for instance, that you are a Woman wanting to join the Woman group. This should be obvious by your username if you logged in with Social Media. Don't see a group you would like? Create your own!
