Knowing some of the teachings its not correct at all.

In a way its like if person A was trying to help person B, but by trying to help they best way they could, it actually made the situation worse. Do the actions of Person A whether good or bad mean they're a bad person?

in the same way, if you are going off personal interactions youve had with people of any religion, or situation, you can be valid in your own regard from what you've experienced. It's not possible to be sent to Hell just for saying you dont believe in God.

Almost same energy as "I dont trust random people". You dont know them, so why should you blindly believe?

If you want to study the Bible history, and all the rabbit holes then you can try understanding those thousands of years of history, then you can make a decision about this random person which people call God. Same thing as doing FB lookup of someone online to see what kind of person they are.

And as a side note: This applies to any religion, but any religion can be considered a cult. There's idelogies they all have a strive to have, but the people, are well, human. They can really be in their own world/bubble, and unless they're trying to intrude and actively harm others, id just say theyre oblivious to their surroundings and the outside world, and wouldnt think much of it. Most likely a bad apple in a huge bunch, but in all cases it depends.
