Why does the dutch pirate take such a dislike to gulliver

There is never a reason given for why the Dutch pirate to such an immediate dislike to Gulliver. Although, it seems his rage was intensified after Gulliver plead with him to take consideration of the fact they came from neighboring countries.

"This inflamed his rage; he repeated his threatenings, and turning to his companions, spoke with great vehemence, in the Japanese language, as I suppose, often using the word Christianos."

please can you elaborate
