Back to the OP - I understand the concern, but I believe that there is a backdrop to all of this.
As our collective culture is forever changing, there are going to be instances and situations where circumstances at very public events are viewed differently by many people. I think the handshakes/hugs are a part of this shift.
However, as we have a community that is quite large and very diverse, there should not be a standard on how we show appreciation or emotion. Case in point - I am not a person that likes to share a 'hug'. I am a person that does not know how to show emotion in times of joy (which is part of the reason my Soccer team gave me the nickname of Hedgehog).
I will say, before my involvement with FRC, I was not comfortable with "the hug". It wasn't until FRC 4607 won a regional back in 2013 that I actually may or may not have hugged another man that was not my family (but this is just a rumor until proven otherwise). This year, however, I think I have openly hugged more people that are not family than I am completely comfortable to admit at this point
So back to the OP: let's not judge people or a community on how and when they show there emotion and gratitude. We are all still working through this strange congratulatory period between people that we admire and those that are receiving an award that acknowledges their hard work.
