You are right, we need to be careful from our point of view to not appear as lecturing towards Newbies, wo still can have huge knowledge about cryptocurrency. Not every Bitcointalk Newbie is a newcomer to crypto. We need always to be welcome and friendy to Newbies here in Bitcointalk.
I would be bold to say, you can lecture me!
It doesn’t mean I don’t know a thing or two about Bitcoin or cryptocurrencies but, you might have an interesting way to put it which might be entirely new to me or even better than the way I have always known it or would put it. At least, what I feel I know, I would share and if it results to what I need to pose some contradicting arguments on, I would as well and not because I want to argue and be difficult but, because I want to learn from it.
Even newbies have got something to teach you know. The ignorance of those who are learning can bring the spark that question which would lead to intelligent discussions and discoveries.
