Well, in India, this argument is used to show that polytheistic religions are 'better' than 'Abrahamic' religions. It is one of the main right wing planks targeted at my people; so let me present a slightly contrarian view compared to the other answers
Religious iconoclasm was very much a part of pre-Christian cultures eg. Roman destruction of the Jewish Temple, the destruction surrounding the 2nd Punic war etc. At some point, it is not particularly possible to separate religion and secular culture into distinct baskets. Take for example, one of the principal arguments that the Chinese government uses for the takeover/retaking/conquest/occupation of Tibet, that the Dalai Lama was running a theocratic serfdom which had to be ended. The Tibetans may see it as integral to their religious identity, but the Chinese don't see it that way. Do events of that kind get classified under religious iconoclasm or secular political disputes?
In South Asia, Hindu-Buddhist relations are in many respects, as antagonistic as Hindu-Muslim relations, and in fact much more antagonistic than Buddhist-Christian relations. Anyone with a passing understanding of Myanmar and Sri-Lanka can easily see this. In Sri-Lanka, the Sinhalese national narrative is fundamentally built on the historical defense of Buddhist society against Tamil Hindu kings and is replete with tales of destroyed Buddhist temples and the trauma around it. Even in India, there has been genocidal levels of violence between Jains, Buddhists and Hindus.
I would also claim that Christian exclusivism is vastly over-hyped. I would definitely agree that such ideas are more a part of Christianity, than say, Japanese Shinto or Chinese Taoism. But the Christian social and political code is still predominantly Greco-Roman and not Jewish. I mean, why does say Nepal trust the UK more than their co-religionists in India. Are they incapable of realizing that the exclusivism of Christianity would make any nation with a Christian culture fundamentally antagonistic towards pagan societies? Well, it seems that is not their historical experience. In a practical setting, Christian societies don't derive their social behavior from theological ideas of exclusivity.
Even in a theological sense, exclusivity was never a big part of Christian belief system. In a mainline protestant setting, I have never heard a single sermon about one god, or why monotheism is better than polytheism. In fact, the main reason Christ was killed was because he went against the strict exclusivity of the time. Evangelicals generally seem bigger than they are because America has such a global cultural presence, but in terms of numbers, they are not really that many.
