At this risk of offending American (?) sensibilities..... In Blighty, sarcasm and piss taking are part of entry level conversation. I kindly suggest this is something you clearly missed when 'arguing with British people'. (The American habit of writing "/s" to signal sarcasm looks distinctly odd to a Brit, as of course it is sarcasm, otherwise they would not have written something so obvious.)
