Said before and I'll say it again - more folk will have been killed in the USA by toasters blowing up in people's faces in the morning than white supremacy, every year.
Do white supremacists exist? yes.
Do you need to be vigilant with them? yes.
Are they a widespread danger? no.
Are they a convenient excuse and straw man for the left, the black racists and all their apologists? yes.
White supremacists will amount to a few dozen thousand militant skinheads and redneck hillbillies splattered about the USA. Figures of ridicule. No more no less.
But the left, in order to make their excuses for black racists, BLM and ANTIFA will always just resort to their go-to position of white supremacy (along with non-existent systemic racism).
Unless folk start being honest then USA will never heal - but it's not in these people's interests to be honest because the wheels come off their lucrative and powerful racism industry. Can't have that.
