Understanding the emergence of strong controversial issues in modern\nsocieties is a key issue in opinion studies. A commonly diffused idea is the\nfact that the increasing of homophily in social networks, due to the modern\nICT, can be a driving force for opinion polariation. In this paper we address\nthe problem with a modelling approach following three basic steps. We first\nintroduce a network morphogenesis model to reconstruct network structures where\nhomophily can be tuned with a parameter. We show that as homophily increases\nthe emergence of marked topological community structures in the networks\nraises. Secondly, we perform an opinion dynamics process on homophily dependent\nnetworks and we show that, contrary to the common idea, homophily helps\nconsensus formation. Finally, we introduce a tunable external media pressure\nand we show that, actually, the combination of homophily and media makes the\nmedia effect less effective and leads to strongly polarized opinion clusters.\n
