i'm not saying its all good though, this is where i would argue that jewish influence on western civilization has been highly adaptive. they came into conflict with us as a highly cohesive, collectivistic, organized national group with a strong racial awareness, and we adapted some of their traits in order to compete with them. christianity emerged as an anti-jewish movement in the late roman empire, as the jews were very wealthy and powerful at the time, and adopted jewish characteristics (obviously, given its jewish origin) such as in-group altruism, out-group hostility (particularly towards jews), intolerance of heresy and cultural uniformity.  and eventually they succeeded in defeating the jews and nearly destroying them, but the collectivism of the catholic church also destroyed antiquity in the process, with purging of criticism of the church, heretical or pagan religious documents and the neglecting and outright destruction of pagan architecture leading to the dark ages
