The line is very clear. We are not those people and we hold ourselves to a higher bar than them. We don't want to descend to their level. Hate for them shouldn't turn us into them.
I'm not sure who "we" is referring to, but if you're referring to America, the Nation of Islam is an American political/religious group based in Chicago that routinely calls for the death of Jewish people (they also advocate for the death of Asians, teach that all white people are satanic, and are anti-vaxxers). "We" already have descended to their level, and yet Twitter allows them to remain.
