The opposite of Calvinist ideas about salvation, yes, but very much in line with culturally-Calvinist ideas about how to live your life. No branch of Christianity can be reduced to its soteriology without distorting it beyond recognition.
That's very interesting. I grew up in a Baptist Church, where 'Calvinist' and 'Arminian' described intra-denominational differences so the 'Calvinists' were broadly similar to the non-Calvinists in pretty much all beliefs except the TULIPy ones. It makes sense there would be greater differences in other denominations.
If you want an interesting and distinct Baptist set of beliefs and practices, the Primitive Baptists are fascinating. They were a prominent group of Baptists in the early part of the nineteenth century in America, but their resolution not to embrace the missions movement cost them much popularity. Calvinist in the broad outlines of their theology, but a lot of significant differences that I think are a little more intellectually consistent. There are still a small number out there.
