I find it a good indication of how pathetic our politically correct society has become that you felt you needed to defend yourself for identifying them as "British" (which is likely what they are) by saying you don't hate British people. SMH It shouldn't be offensive to call someone British. or Nigerian, or Japanese or American or anything for that matter. Sounds to me, by your description, that they were likely British (likely by their accents), and they were children (likely by their young voices). So just leave it at that and stand tall. :)
