Infighting
1)When you and/or someone else Criticize a friend or a Political
Party, or a News organization that lean towards your political affiliation, but don't agree on specifics and practicalities that fit your niche of that political affiliation.
In other words, you have the same
broad worldview of how things should be but you disagree on the specifics.
2)One might blame another for "shooting in the tent" when he criticizes and chastises members of his own political
party while the opponents of said
party can gain power on the back of "Infighting".
The metaphor is for a guy that has a guy in a tent and has beef with one person and tries to shoot him while endangering his friends as well.
"Man, you really have to stop Shooting in the tent. we'
re all on the same side after all."
"You don't have to agree 100% and still work for the bigger issues.
But if you keep shooting in the tent you
will bring all of
us down!"
