I work with a fairly large and diverse IT team with age ranges from 22 to 60+; a lot of this involves disagreements as is natural with any conversations with a large group of people.
Discussions with the younger demographic are far more productive and faster as they're quite specific in their statements and when there is a disagreement, they put it out there fairly openly, explaining intent and feelings, and when I reciprocate, we get to a faster understanding of one another and any potential misunderstandings we might have had, view points we hadn't considered, or parts that aren't clear for us. The initial conversations take a bit longer, but ultimately end up with all parties understanding the situation well. It's quite healthy I think.
With the older age group, I definitely know _when_ they're angry or upset about something or when they disagree with me, but I rarely know _why_. Trying to slow down the conversation and have the same "help me understand what you're thinking/feeling so we can better communicate" often is not received well, and while the conversations are more direct initially, they last far longer and result in more tirades, walls of text, and dozens of arguments with loose or no connection to the topic at hand.
I don't see the younger persons as being sensitive, I see them as being specific; I think they're better trained socially to express themselves and reflect on their reactions and their state, and embracing this by participating in the same way is very freeing. I can have what might be considered difficult discussions (corrections, disciplinary actions, etc) and understand that while likely the conversation partner is not happy, they feel understood, I've presented my point of view, and when presented with new information, all sides have been very receptive.
With my older colleagues, the same sensitivity and emotions are there, but I'm far less aware of it even if I specifically take actions to show I want to understand more.
There is definitely a culture clash, and I think that the reactions of "snow flakes" and "triggered" are not accurate, and it's more about two persons separated by a common language failing to communicate. Given how well conversations with my younger colleagues go, I'm more inclined to prefer this model.
