To use your own example, once an acorn always an acorn?
There are some religious groups with few if any cult-like tendencies such as (generalizing quite broadly) diaspora Buddhism, Reform Judaism, Unitarian Universalism, some 'mainline' / liberal Christian churches, and some Hindu, Jain and Taoist groups. Presumably even some Muslim groups too

Trying to say that religion always = cult makes the word redundant and utterly useless. It's not even etymologically warranted (Latin
cultus means 'worship'), since not all religions involve worship.
How many grains of sand are required to make a heap of sand? How many whiskers of what length are needed for a beard? You're engaging in what's sometimes called the continuum fallacy. The relevant features of cults in the Jonestown/Heaven's Gate sense are their insular, unquestioning and usually authoritarian nature, and those traits can be mapped out on a continuum. It's a rough approximation, but the more numerous a sect becomes, the more that insularity is inevitably breached - except in cases where it becomes the overwhelmingly dominant sect of its country/region/language I suppose - with its membership becoming more diverse and exposed to or open to different perspectives.
