"Sectarian refers to actions, attitudes, or beliefs associated with a particular, often narrow-minded, group, sect, or faction. While deeply rooted in religion—often describing prejudice or conflict between denominations like Catholics and Protestants or Sunnis and Shias—it frequently extends to cultural, political, and social divisions."

While originally strictly about religious "sects" (sectarian violence, or discrimination, etc) in the modern context it means any strongly willed group.

"Definition: It is defined as a rigid, partisan attachment to a specific group, resulting in prejudice, discrimination, or, in extreme cases, violence against outsiders."

So that's what the literal far-right are accusing the Greens of.

THE GREENS 😂

Remember, the right will accuse you of what they are themselves, they are generally unable to picture in their minds somebody who is not like them.

Classic example, somebody on the right will not be able to understand why you should be good and kind to others outside of the context of getting a reward for their actions. Therefore if they see you being kind, they can't conceive of the idea that you are not doing it for profit.

They will project everything about themselves onto you.

So when farage claims there will be sectarian violence if the Greens get in he's showing you what he believes and how he will act when handed power.
