Are there 30,000 war fronts?

A popular Catholic trope is how sola scriptura spawned 30,000 denominations. But that's a dumb way to count. Most Protestants affiliate with a handful of major denominations or corresponding faith-traditions, viz. Anglicans, Lutherans, Baptists, Pentecostals, Presbyterians, Wesleyan Methodists. And there's overlap in these groupings. Arminian Baptists, charismatic Baptists, &c. By the same token, independent churches usually adopt one of the off-the-shelf faith-traditions represented by a standard evangelical denomination. 

Likewise, although these break down into subsets of denominations, they belong to theological families. Different Baptist or Presbyterian denominations belong to the same theological families, sharing the same essentials and distinctives. Their doctrinal positions are often identical. The main dividing line is between observant confessional denominations and progressive denominations. 

Likewise, debates between Catholic and Protestant usually revolve around a stereotypical menu of issues. On the Protestant side, sola Scriptura and sola fide. On the Catholic side, the papacy, number and nature of the sacraments, purgatory, canon, cult of the saints, contraception. 

Although the menu can be widened and deepened, Catholic and Protestant apologists don't debate thousands of competing positions, or hundreds of competing traditions, or even dozens of competing traditions. The disagreement almost invariably circles around a set of endlessly debated core issues. Catholic apologists aren't fighting on 30,000 different war fronts.
