Thank you for posting the list OP.
Some deaths have always captured the public imagination more than others.
Why did Sarah Everard get more attention than Richard Okorogheye, or Bibaa Henry and Nicole Smallman?
Why did Gabby Petito get more attention than Lauren Cho?
Why is Nicola Bulley currently getting so much more attention than the other missing person cases?
"Missing white woman syndrome" is a real thing, where they get disproportionate level of media attention, both as missing and murder victims.
Sophie Lancaster was another teenager killed for being different - a goth in her case. There was a strong reaction from within her own minority community, and beyond - including a BBC programme ten years on and a Coronation Street storyline a couple of years ago. I don't remember people questioning the motives of those wishing to commemorate her life and death or claiming it was being politicised and that was in some way wrong.
We all find ourselves finding more connected to some cases than others. For me, both the Sarah Everard cases and Joanna Yeates cases were far too close to home because I was a young white woman living in the area at the time / very recently and had walked the routes they walked. Sophie Lancaster felt relevant to me because I was something of a goth myself at the time. Quite naturally, a lot of LGBT people will feel connected to the Brianna Ghey case because they are part of the same minority community.
There's some people on this thread who need to take a long hard look at themselves and why they are opposing vigils for a murdered teenager. If you feel there other murder victims haven't had a vigil and should have then you are free to organise one of your own.
