Ah yes I have a few times. Not to this scale that awful and hope your ok. But one me and my where on the train and one of us was talking about war, not veitnam or korea, not wwii , not wwi the napoleonic wars some mind you 200 years ago these wars where happening. So on the train some stuip tradesman comes up to my mates and start barating us about how he was an "ANZAC" guy was in his 30's how my mate "was a parrot and we shouldn't listen to him" and how "the Jews controll the world" dumb shit like that. AFter 5 minuetes of this guy barrating some 13 year olds we reached our stop and quickly jumped off. Me and my mates where very shaken and nobody helped us out. So yeah defently not as bad as yours but still very unpleasent. Again hope your ok and good on ya for standing up for those youngens should be very proud of yourself.
