Folks are just on this here Internet this morning making shit up. Just acknowledge the facts and stop with your stories, examples and experiences. It's all in your head or your misinterpretation of events. So...
White people who mate and procreate with black people cannot be racist.
White people who are nice to at least one black/brown person cannot be racist.
Microaggressions and the warped perceptions of the sensitive.
Racial slurs? You spend too much time on SM.
Racism is imagined and just something used to shut White people up.
This is Britain, where racism doesn't exist.
Acknowledging racism and speaking about/confronting it is why there's so much support for Reform (and remember, Reform abhors racism. They even have non-white MPs (✅️).
I'm sure I've missed other pertinent bits, but I've ingested enough for today, so ✌🏾.
I can't glean any racism in what the OP has typed, but given so much grace is given on MN for any hint of SEND, I wonder why that hasn't been mentioned here. It's unclear who made the accusation and if they're the person with SEND and if that factors into what's going on here 🤷🏾♀️.
