I mean yeah assessing people on an individual level is different from collective. Look at the collective history of white people over the past few centuries and it's pretty logical why PoC are going to have their guard up. When white folk came to your country as a group, historical precendent is such that killing and/or stealing are high on the list of potential outcomes.
The Democratic party supported the civil rights act of 1964 in the US, which ended race based segregation. Since then not a single democratic presidential nominee has won the majority of the white vote. That's some pretty dark shit.
This doesn't mean that any single individual white person is presumed bad.
