This phenomena is going to be a purely leftist oriented one - called the "Circular Firing Squad" - which I first saw here.

It's similar to the mid-2010's right-wing talking point: "What happens to the LGBT if the Muslims gain the voting majority?" or the current division occurring within feminism - between "trans-exclusionary radical feminists" (ie: most of the original feminists) and people who think trans-women are (literally) female.

Not taking a stance on any of this - just pointing out socio-cultural and logic anomalies.
