Excessive apologies can feel disingenuous and perfunctory. That makes it difficult for me to know when an apology is genuine. That erodes my trust.

Excessive apologies can signal to me that the other person sees me as a threat, and I don’t want to feel like a threat, so I feel attacked.

But I could also choose to interpret excessive apologies as a sign of past trauma, so I could choose to have compassion and patiently ask the other person to talk to me about what’s going on. I can share how I feel and hope that they feel ready to discuss what’s happening for them. Patience would be key.

Now it depends whether you mean actual DEI or the nonsense that companies do in the name of DEI or the unfortunate overreaction that some people support related to DEI due to the resistance to actual, reasonable, sensible DEI.

“… regardless of all other factors…” sounds like the second of these.
