No, it's fine.
I've grabbed your Collins as an example - I promise it's not been cherry-picked, it was the first I clicked on!
"If someone converts you, they persuade you to change your religious or political beliefs. You can also say that someone converts to a different religion."
Would it qualify as changing my religious beliefs? I think so. It's you that's inferring that it needs to be to another religion.
Ok, second part.
"I get that a large part of Abrahamic religions in particular is to obey and not question, as well as theism being necessary to be adopted into the religion"
No you don't, because you're wrong. I don't mean that in a harsh way - it's easy to look at listen to all of the hard-line religious folk and think that's the norm. The truth is that they're weirdos.
A big part of most Abrahamic religions is questioning the dogma, theology, even the scripture. It's been this way forever too.
And yes historically, bad people have used religions (and still do) as a pretext for horrific atrocities, but unfortunately that's a problem with any organisation that places too much power on an unhinged leader.
Look, an example might help. A little while back, the Church of England put out a statement about how they didn't intend to change their stance on not allowing gay marriage in churches. It was, to my eyes, an utterly unnecessary statement to make, and moreover, completely at odds with the "unconditional love" message.
I asked my vicar if we could talk about it and explained that I don't feel comfortable being associated with a religion that publicly makes statements like that.
I found out that she herself has performed several same-sex marriages, just not in a church. As have many of the other vicars around here. Some haven't. Her mentor in the church is transexual, not secret - she's written a book about it.
The truth is that the upper ranks of the Anglican church are trying to prevent a schism with the more hard-line Anglican churches in Africa. The statement was just one of many that have been put out, it's just that this one got attention from the press.
The rank-and-file vicars don't even share exactly the same theology as each other. Like I said, many officiate same-sex marriages, some will not. Some believe that when people die, their souls go straight to heaven or watch over us, some do not (why wouldn't they? Well, it isn't actually in the Bible).
There's a wide, wide range of interpretations and you are encouraged to keep asking questions.
Like I said, it's easy to look at the loud people and think they're the norm - but it's not the case. They're the very, very vocal minority.
Yikes I've written way more than intended. I hope that helps!
