I see people saying their vote doesn’t matter when they’re in a highly partisan district

I see people saying it when they’re in heavily gerrymandered districts and deeply disenfranchised states. Dems have been playing the “Just go out and vote!” game in Florida for a quarter century, and Repubs keep finding new ways to yank the football. Even ballot initiatives don’t work, as the Florida gerrymandered legislature just reverses out whatever voting rights or decriminalization laws the public passes.
