Hi IFTNP -
Or is it something that is impulse? (they really think this way... vs. thinking "every non-JW is the Devil"
It's subtle persuasion. Most don't fully realize what they are saying as they say it. You will hear it phrased in so many ways at the meetings, too. All the time.
If they came out and said "All non-witnesses are following Satan and will be destroyed soon at Armageddon" - would you really keep studying? They try to soften what they really think so as not to scare you away. In reality, JWs have a true 'Us vs Them' mentality.
For now it's presented as 'something to consider.'
Later it will be 'something to watch out for'.
Then 'something to avoid'.
If/When you are a publisher, it will be one measure of your spirituality.
"Bad associations spoil useful habits" will become a mantra for you.
Don't remember if I'd said it before, but Welcome to JWD. It really is a good place to learn and 'be'. Whichever road you choose (you're 17 - you have many choices!), you will find support here. You may be challenged a bit, but you will be supported, too.
I enjoy your posts. Looking forward to more.
Aude Sapere (meaning: Dare to Know; Dare to Have Wisdom/Knowledge)
