The schism between Ahl al Sunnah and Shias is not about race. The shias are an innovative and dark cult.
Some Shia are considered Muslims, and some Shia are considered Kufaar. Various Shia have different beliefs: some have beliefs which constitute Kufr, whereas others do not. Shaykh Muhammad ibn Adam al-Kawthari says:
According to the classical and the majority of contemporary scholars, there are two types of Shi’as:
a)Those that hold beliefs that constitute disbelief (kufr)…shi’as that hold such beliefs are without a doubt out of the fold of Islam.
b)Those who do not hold beliefs that constitute Kufr…Such Shi’as can not be termed as out of the fold of Islam, rather they are considered to be severely deviated and transgressors (fisq).

Shaikh Abdul Wahab al-Turayree, a professor of Al-Imam University, says:
We cannot say that all the Shî`ah are unbelievers. On the other hand, there are many sects of the Shî`ah who advance claims that are tantamount to unbelief. Anyone who believes such things would be an unbeliever.

Shaikh Muhammad Salih Al-Munajjid of Islam-qa.com says:
What we say about interacting with the Shi’ah depends on the situation. The innovated beliefs of the Shi’ah vary. If it [their belief] is something that does not put them beyond the pale of Islam…[it] is rather regarded [merely] as drifting away from the right path [as opposed to Kufr]…[in such a case] they are Muslims who have committed acts of innovation and sin that do not put them beyond the pale of Islam.
