How is racism relevant to modern times?

Racism will be relevant as long as there are systems in place that uphold it. The murder of George Floyd last summer and the ensuing protests highlighted the still-prevalent racism and anti-Blackness at the heart of American policing. The rise in racist sentiment against Asian-Americans during the pandemic, and the continual use by Donald Trump of the racist phrase "China virus" provoked a number of xenophobic attacks against Asian-Americans. The dehumanization of immigrants, especially from Southern and Central America, is enforced through organizations like ICE, whose detention centers shed light on some of the truly horrific conditions undocumented Black and brown immigrants are subjected to.

explanation:

the present continuous is a verb tense which is mainly used to indicates that an action is in progress at the moment of speaking.  

it is formed using: person + verb to be (am/is/are) +verb + - ing form  

example: i am studying at this moment .

in addition, the present continuous is also used in order to express things that will or will not happen in the near future.

example: i am having dinner with some friends tonight.

the speaker sometimes   uses it   to express that an action is repeated and it causes irritation on the part of the speaker

example: my sister is constantly complaining about everything.
