I can't speak for this poster OP but it worries some of us that some people have become so terrified of things which aren't that frightening. It's a concern for us as a society that we've become so scared and risk-averse.
Visiting Paris or London is really a pretty safe to do: people have been visiting both for millennia and in the vast vast vast majority of cases they have a good time and come home unscathed. When I was a child no one would suggest that these cities were "dangerous": it just wasn't on anyone's radar, beyond just taking normal precautions.
Something has changed in the past 5-10 years: people are jittery and anxious about stuff which they used to be able to take in their stride. I think a combination of post COVID anxiety, declining living standards and toxic politics is at the heart of it but I can't know for sure. But there's a worrying level of anxiety and a lack of basic critical thinking in suggesting that a visit to an affluent, well run and large European city is intrinsically dangerous.
Also many of us live in these scary big cities and have normal, happy, fulfilled lives. I've lived in London for over 30 years and raised a child here and experienced virtually no crime at all. So some of us find it irritating and mildly offensive when people seem to suggest that our home towns are terrifying crime-ridden cesspools.
