"Worldly™ people won't love you like we do."
The implication is that JW love is much, much better than what you can find anywhere else, which is patently FALSE.
Looking at the phrase in retrospect, it is true, isn't it? You'll never be "loved" by anyone else the way the JWs Love™ you.
JW Love™ = shunning when someone disagrees with the WTS, forcing children to stand out like sore thumbs at school by Standing Up For The Truth™, conditional friendship, and forgetting people as soon as you're out of the congregation.
Worldly™ love = respecting differences of opinion, even if you disagree; kindness (charity) when it's most needed to complete strangers; sense of community and wanting to make a positive difference with one's life, accepting people as they are, etc.
