IMO the lack of conflict here is due to:

(i) Early adopters having more in common with each other (e.g. love of tech); and discussions are more about building than politics

(ii) Even where we don't have opinions in common, we don't feel that 'wrong' opinions should be condemned or censored

(iii) Zaps & tips encourage positivity & cooperation rather than conflict

(iv) Also, lack of ease of quote retweeting helps, IMO: heaps of quote tweets on the bird app are encouraging followers to mock someone else.
