Racism is an overt act of bigotry, so to define it in such broad terms is too black and white. While there are still some racists and boots, most aspects of society present an equal opportunity to everyone, regardless of race, gender, and sexuality. When woke culture criticizes something like the criminal justice system, they conflate racism with policies they disagree with.
The breadth of things that become racist and oppressive through a woke worldview is too wide. Many of these can be explained by other factors, such as wealth inequality, crime, health, and education. Considering this, activism is misplaced when we should be discussing other issues that ail disadvantaged populations.
