At 29 years of age, as I get older, I know the history of America's treatment towards Black Americans and the ongoing racial injustice and anti-Black sentiments, among other racist systematic hardships.
I definitely do not think highly of or view White people, and pretty much anybody who isn't Black fondly these days; I will say I'm slowly transitioning into a Black Nationalist mindset in that I don't care, let alone have any feelings of sympathy or empathy for non-Black people whatsoever.
That's not because of any sociopathic and sadistic lust to see others suffer but rather coming to understand that Black people have to look out for themselves because this country and many of the people within don't give a shyt about us, so I've embraced the importance of prioritizing our own over anybody else

.
I'm all about Black people, and as I've gotten older, my mentality has moved to a stricter focus on our well-being and being a big supporter of us.
There is a stark difference between Black Nationalism and White Nationalism. It's deeper than what the surface would suggest until you take a deeper analysis of the two sides.
Black Nationalists don't advocate or promote hatred and violence towards those who aren't Black; we can envision ourselves living in the world, the same country with individuals of all different races and ethnicities, we're not striving for an all-black ethnostate, or seeking ethnic cleansing of other races and ethnicities through violence, the idea that other people who aren't Black existing next to us and sharing the same air isn't problematic.; we just want justice, peace, freedom, equal rights, etc.
White Nationalists are the opposite; they can't fathom living in a country or a world in which other races and ethnicities exist, breathing air. Their goal is to destroy and eliminate others through violence and systematic measures while spreading hatred and rejoicing and relishing in other races and non-white ethnicities' pain and suffering, whether it be through racial violence, economic hardship, and systemic (prison system, police brutality, healthcare disparities, etc) injustice, among other things considered taxing on one's psyche.
