the first thing you think is "oh my god some judgemental person attacked someone who is different", but this line taken from the first article....
"She said the couple appeared to have been "pushing and pulling as a joke" moments before the train pulled in."
Suggests that it could of been just an accident... I really hope so. But even if it were would that tiny bit of important information see the light of day? hhmmm. Sad event either way.
