Intentional bigots -create- conflict and strife by the way they treat and talk about others. It is their unfair treatment or words towards others that are the causes of strife. They will typically make it seem like people responding to unfair attacks are the ones “creating” the strife. They are not. It’s the bigots who create the strife.
Creating strife serves to “divide and conquer”. This is a super common and still very effective tactic usually used by folks -already in power- to maintain power OVER others. It is often deployed in subtle ways to mask the true intention (the true intention is to fracture alliances among fair minded people so they will not support each other in times of need).
