As individuals we can raise our own awareness of what constitutes a racist incident.
For example, microaggressions, explained in this BBC blog are:
“Brief queries, comments or actions sprinkled throughout day-to-day life that make others – particularly those in marginalised groups –feel bad about themselves.”
Also, micro-incivilities, explained by Professor Binna Kandola on the Advance HE website. He says:
“The blatant forms of prejudice have been called 'old-fashioned' racism,and can include verbal and physical abuse, as well as overt stereotyping. It's the sort of thing that many of us could never imagine ourselves doing. 'Modern racism' however is a different thing altogether. It is subtle, oblique and indirect in its manifestation, yet its impact on the people on the receiving end can be just as devastating, and sometimes more so.”
