Story is false, nobody says White Trash in the UK, that's an American thing.
For the people who said I was lying, this is an audio recording of the child's screaming which trigured off the racial abuse from the mother:
Racist Mum's Child Screaming On The 89 Bus - Shooters Hill, SE London (20/02/2013)
Published on 22 Feb 2013
Imagine the scenario. You've finished work after a long hard day. You get on the bus to go home and there in the middle of the downstairs seating area is a child in a buggy screaming its head off nineteen to the dozen. All you want to do is find a seat, sit down, get yourself comfortable and relax for the 45 minute journey home, but you can't all because a child has decided it wants some crisps from a bag that its selfish mother has opened for herself to eat. The screaming continues and the mother just sits there making no effort to calm down her distraught child. The noise isn't a problem in her eyes, everyone who has paid their fare should just like it or lump it and anyone who doesn't like the noise is scum. The screaming gets louder and louder until you've had enough and have no choice but to shout "OH GOD" at the top of your voice to let your anger be known. You are then threatened with violence and called a c**t, a paedophile and white trash by the child's mother for being an intolerant bastard.
This is a true story that happened to me on my way home from work on the evening of 20/02/2013.
Is this level of noise acceptable on public transport? Was I wrong to say something? Even the driver of the bus was angered by the noise. Listen to the audio recording I made on my phone and judge for yourselves.
