He misspelled “vivid tapestry” - That’s a play on “vivid diversity” (EG colorful)
Here's a hint: proggies issue apologies for subhuman invasion by expressing negative effects in positive terms. Such as "part & parcel" (Londonstan), "sexual emergency" aka struggle snuggle (Sweden), "cultural enrichment" or "vivid tapestry" ie "diversity is strength".
So what gaijan was cleverly referring to were the rewards of being 'enriched' while living among the 'tapestry' of gang & drug violence in ag cities such as Salinas & Watsonville.
