I believe most of the bitcointalk users are long term holders so they don't really care about the drop of the bitcoin price in the short term and as you said they expect a rise each time a drop happens.
Long term holders means they are the ignorant for current markets fluctuations. I have seen many people who do declare themselves as long term holders but when they see bitcoin hitting some big price levels and they are making some 2x or 5x returns for their capital then they are immediately changing their long term into day-trading. I guess, OP is asking us like, is there any change in our faith on bitcoin's future.

What have changed in the recent times so that I need to change my mind ? I am a long term believer of bitcoin and its future hence the rise and fall of bitcoin prices will not impact my decisions on holding it for my next generations; yes, I am not just saving bitcoins for myself like for my retirement, I have planned up some big portion of bitcoins for my grand children. I do believe into bitcoins regardless of how its market behaving.
