Anyway, the thing about Protestantism is two fold first I take shots at them because a lot of them act uneducated and sometimes ask questions like "are you catholic or Christian." Which I find kind of disrespectful towards my Catholic brothers since they are an ancient Church, true it has occasionally slipped into corruption but all man made institutions have.
As I pointed out before, I haven't seen such crap here, so lashing out at the Prots here who haven't done that to you or to the Catholics is, well, kinda being an ass. If they do, then sure, fire back (to the degree which civility allows), but the constant sniping at the Prots here, most of whom come from the conservative branches that haven't been corrupted as far as I can tell, just serves to divide those who should be allies in a larger ideological conflict.
The second issue I have with Protestants is a bit more practical. There are so many of them. I don't mean in total numbers I mean in different sects and denominations. It makes it hard to know where one group lies, some are absolute heretics who aren't Christian with women priests, and gay clergy and saying shit like trans people are divine. But others are perfectly acceptable and have good ideas on how society is to be run and how Christians should act in regards to morality like conservative Baptists. But even with them this second problem raises it's head you can go through a city and see a dozen first Baptist churches, and I always think when is the second one going to be built? Now you don't have to have a world spanning authority that obeys one man, I understand Baptists don't want a new papacy. But some order and unity is needed so that Baptist Churches in a city answer to one bishop of that city, and that Bishop answers to a higher Bishop in charge of the nation, or the state they are in for America. I mean I can understand if the Church is being actively oppressed like in China or communist Soviet Union you might need to keep it small and decentralized but America hasn't reached that level yet.
That I can understand, heck, most Protestants can't keep them all straight anymore, as many are even now undergoing their own schism.
But, to greatly simplify, there's two main groups of Protestants in the United States: The "Mainstream" and the "Evangelicals". The simple way of looking at it is that Mainstream Protestants are those who's church organization date back to the American Colonial period and very early Republic Period (IE, before 1800). These are groups like the Presbyterians, the Methodists, Anglicans and Episcopal, etc. Basically if it has a formal name you've heard of that isn't "Baptist", then it's probably a Mainstream Protestant Church. These Churches tend to be on a national scale, have considerable history and money, and be the organization that founded many prestigious universities in the US.
Evangelicals mainly developed in the middle 20th century as a grassroots, for lack of a better term, reformationist movement that grew out of the Fundamentalist who split off from the Mainstream Protestants when they began embracing Modernism in the early 20th century. They vary wildly in size and origin... some with not so clean origins while others are just organically grown. They lack hierarchy and tend to be much more individual standing Churches due to this origin (bear in mind, they functionally originated from the orthodox Christians who were jettisoned by the Mainstream Protestants, and thus stripped from the already existing hierarchies and having no hierarchies to enter into), some have gone on to create larger church hierarchy, while others maintain more independence. Given that the movement is less than 100 years old, lack of those hierarchies make sense, they've been slowing having to build up an entire alternative support system from the ground up, all while under constant siege and marginalization by society at large (and, also due to this disjointed nature, it means individual churches can be corrupted fairly easily, and there's no shortage of grifters who set up cult of personality megachurches who fall under this title who are of dubious orthodoxy).
The exception to this is the Southern Baptists who originated as a geographical schism of the Baptists over, well, segregation, but since have spread out from that and are no longer strictly a "southern US" organization (though they still are more common in the South). While having a very different origin than the other Evangelical sects, they tend to be lumped in with them rather than the Mainstream due to their origination in the 20th century, rather than the 18th or 17th century.
Between these two you have a lot of various Christian "Others". In the middle to late 19th century you saw a bunch of moonbat "Christian" sects or dubious orthodoxy pop up across the US, from the Mormons (who were most successful) to things like the "Christian Scientists" to the "Seventh Day Adventists" and many others. These are usually tracked as their own thing or as "others" since they tend to be really small if still around. Most are of comparable size to, if not smaller than, the number of Orthodox in the country, and so while some of them have some truly heretical
