Where are all the Racist People?

Okay it might sound like a weird question but hear me out.

All over the Internet I see constant racism against my people, so that has painted a particular image for foreigners in my mind.

But my every foreign experience has been pleasant, like everyone is so nice and helpful. Especially white people.

Like reading history makes it sound white people are somehow responsible for all kinda horrendous suffering and oppression. But they come across as the nicest and most helpful people on planet.

I have had few minor racist experiences, but in those moments it felt like the person was asshole and not a particular demographic.

Internet somehow makes it feel like that hatred is bigger than it actually is.

Am I missing something?…entire picture is not coming together in my head.
