If we think about IMVE, it includes gender-motivated extremism, so incel certainly falls under that. However, there's also some intersection very often between incel and what we might think of as more traditional elements of the far right—even white supremacist groups, for example—in that there is also inbred misogyny and traditional fascination with or commitment to traditional gendered roles and gender values within many elements of the far right. They find, I think, a natural affinity among one another.
We're seeing more activity among incels, whether related to far-right groups or not, but we're, thankfully, also seeing far more research in that space that helps us to understand both the peculiarities and the similarities with the far right.
