What? Why?
You created a narrative that any opposition to your opinion will be instantly regarded as racist. (That said, I disagree with the prejudiced person above)
That is obviously true. However when someone is describing thier personal experience, that context is quite useful, which was clearly what was going on in the original comment.
For example - As a gay man I notice subtle prejudice against me in the use of "gay" in negative connotations. (being gay is relevant to the experience here)
