You are assuming that everyone has actually experienced trauma, I'm saying that what a lot of these people feel is traumatic because they weren't equipped with the tools to deal with it in the first place.
If you get in a head on collision in a 50 year old car with no seat belt, you will likely die at most speeds. If you do the same in a brand new car with all the safety tools necessary you can walk away completely unscathed. Or somewhere in between- each collision happens in it's own way.
We're taking our kids today and stripping out their air bags. I'm saying that if a discussion, even if heated, renders you generally traumatized AND you weren't a victim of some abuse or 'real' trauma, it's because the people who had a hand in raising you completely failed you. I'm not saying you're not traumatized, I'm saying you wouldn't have been if your parents, educators, and elders did their damn job.
