How weird :/
Have the vandals explained why they're doing it or are the museum etc guessing?
The naming of boats and cars as female is a bit weird and I'm sure there's some feminist analysis knocking around somewhere about it... But even as someone who gets exercised from a feminist perspective about what many would consider pretty minor things, I can't get worked up about ships being female...
The assumption here is it's TRAs, I bet in the wider world this will be imagined as the work of crazed feminists!
