You’re picking your nose on this. The differences you imagine are not real. Even the Arminians still share the same belief as to the basis of salvation; they just take the fearful read on a couple of verses, which weakens their faith a little, but the effects thereof are small and mostly personal.

Well, that is your explanation. I think it goes beyond that. In my town the largest Presbyterian church just left for another one. I know many Baptist churches around here that don’t do missionary and fellowship with other Baptist churches [and by definition, Baptist churches are independent of each other] because of King James vs. NIV, because some have different eschatalogical views [most of which are all heretical anyway], the health-welfare Gospel preaches some crazy stuff, and none of at the doctrinal level agrees, don’t get me started on the various types of pentalcostalism because by claiming the Holy Spirit speaks directly to the individual, anyone can come up with something different and start there own little Pentecostal church and like minded followers will go.
You can try to spin it all you want. The Gordon-Comwell Seminary study, and I will add it is a well done scholarly work is a historic Reformed-Calvinist seminary and there data does not seem to pick any noses.
One of their links talks about 9,000 denominations that they have detailed data on [I could not get to the data as I am not a member of their site].
The reality is Protestantism will always continue to fragment into more and more and more groups because the authority rests with “me” not a Tradition that was passed from the Apostles down to the Early Church Fathers, expressed in the early Liturgy of the CHurch, the Creeds and the Councils.
Are there some Catholics who reject teachings and dissent? Of course, I would be ignorant to say otherwise, but they are “dissenting” because there is at the Doctrinal and Dogmatic Level, a clear teaching on theological and moral issues so a bad Catholic and one who says they believe in women’s priest, or think abortion is not a sin, or believes in same-sex marriage or believes in euthanasia or believes in some nonsense about the Trinity or who Christ is, denies the resurrection of the body, etc, etc, etc, is a dissenter and in some cases, depending on what is being rejected, a heretic.
In Protestantism, not the case as in the end, even if one says well the Bible says this. All you get is someone telling you, well I think the Bible means this so what do you get with this Protestant notion of stressing the “individual priesthood of all believers” apart from the COmmunon of the Church, is every Protestant theoretically can become their own Pope.
