Sucking Cocks on Train

When I see clips like this I always wonder if there'd be any cultural differences in reactions if Mr & Mrs. Joe Q. Public in a given country suddenly came aboard and discovered such shenanigans? I'm guessing your average Swede would give a disapproving stare before sitting as far away as possible and pointedly not looking in that direction at all. Would citizens of other countries be more morally indignant or aggressive in condemnation? I see the poster is "an expat" in Japan. What about the mild-mannered Japanese for example? And would it make any difference if the "offenders" were Japanese or foreigners? I imagine Americans would be amongst the groups most loudly morally offended and others, like the Brazilians most laid back. What do other people here think?
