So, a Columbus Day Parade is going on down the block ...

John Oliver's video doesn't come up, but others called out Columbus Day. The best path might be to use it to ponder the complications of the situation, of 'our' history. It is also wrong to single out "Columbus" here, but can be a symbol of the excesses of the times. Any half-way credible description of the history is at best unpleasant, if not quite as extreme as the perspective expressed here. The "dog food" bit is news to me, but often cited.
