Why does most people dislike blacks?

Most people what?

Who are most people? Skin is skin, nothing else but melanin and what we wear

Based on what grounds ?

Why do? I don't think many do but everyone thinks what they want. Skin is skin as Lady said. It's who you are inside that counts.

if anyone wants to date me maybe I can get acquainted but for women only 🤣

The ones that do, have fear, guilt, and insecurity in their heart, and become acidic in nature, and they aren't worth a turd in the toilet.

Down here in the Treme, New Orleans, black people have created everything this city stands for, Creole and Blues music, and some of the most amazing tasting food on this planet, inventions, business innovations, Zulu Organizations, and numerous festivals, including Mardi Gras!
(Mardi Gras Indians are a mixture of black and local Native Americans)

Many will not acknowledge these facts to this day. However, there's more of us in this city that do! Laissez Les Bon Temps Rouler!

Who Dat Nation!

Why do most people dislike blacks?

I don't think most(majority) do, but those that DO feel that way IMO

Ignorance and fear
Same with religious intolerance.
Learned behavior that starts young.

Lots of haters out there so it's not hard to find like minded folks to reinforce your beliefs and amplify 'em as well.
