Were the Celtics as peaceful as their lore?

by SourceDestroyer

I just finished reading a book about Irish Welsh Britannia and Scott ancient lore and wow it granted me such huge insight to how much these people avoided fighting and seemingly attempted to make up for insults and mostly honorable people. NOTHING like the movies. Is this true to history or is it just lore?

It would help if you posted the name of the book you read, as no-one can know if the book is accurate without knowing what it is
