I think what the OP is getting at is that in a widely attended work meeting for people like her to be labelled as victims may make those people feel singled out, othered, or patronised.
It doesn't mean those people haven't been victims of racism its more i think, that shes saying that she would feel more comfortable with phrasing like 'may have experienced racism' rather than 'are victims of racism'. I guess the first implies a transient state of being and the second more of a passive consistent state of being, I'm not sure?
The OP was invited to give feedback and said some might feel uncomfortable with it, she doesn't seem to indicate she was speaking for everyone. Certainly her experience chimes with conversations I have had with Indian and British Indian people at work, mostly men, who would feel patronised by being labelled victims in front of their work colleagues.
Of course that could also say more about what people take from the word victim, rather than the actual meaning of the word and maybe the issue is how people hearing it perceive victims, I don't know?
I do know if it had been raised in my workplace it would have sparked a respectful conversation, and would not have raised eyebrows or caused a colleague to message another going 'what was that all about' and being disapproving. I also wonder if the poster hadnt been a female POC whose recently been promoted whether the reaction would have been different.
If im honest I would find it slightly wierd to be called into a meeting for a white man to teach me about how I was a victim of racism, it feels like a rather heavy handed tick box exercise that, if the OPs experience is anything to go by, wont foster an environment where people feel empowered to discuss any of the topics raised which feels like a wasted opportunity.
