Religions become popular when the survival/salvation of the people is at risk, or when a unique benefit is promised as a reward for membership. When neither of those motives is operational, religions tend to devolve into communities of special meaning. In our day, some Christians are committed to social justice, others to doctrinal purity, others to pro-life/anti-abortion campaigns, and still others to inclusivism, etc. 
The societal pressure to which you refer is being replaced by the pressure to state what one truly believes instead of remaining in the crowd and pretending to accept everything. I think that's healthy for the church, but sooner or later it will require a restructuring that recognizes this heterogeneity and doesn't make believe the old one-size-fits-all parishes still make sense, if they ever did. We could anticipate that restructuring by refusing to support the diocesan system, and that is pretty much what is happening, as this article shows.
