I think I'm a bit older than some folks, so perhaps that colors some of my perspective, but I remember a time when many things were different, one of which was the manner in which physical contact took place in the workplace. Over time, some physical contact became correlated to often with a form of abuse. The rational, mature, and responsible reaction to this was to have people avoid anything that has the propensity to perhaps be confused with abuse, i.e., to avoid physical contact in the workplace. Has the workplace lost something as a result? Perhaps. But the benefits far outweigh those losses.
Of course, folks who don't respect the feelings of others tend to refuse to acknowledge that. They often only see the down-side because they were never personally subjected to, and/or never would have been personally subjected to, and/or think they would never have been personally subjected to, the abuse. So they fail to integrate into their evaluation the negatives of the old way, instead just focus on and bemoan the negatives of the new way.
What is greatly needed in this situation is similar to what was needed in that case of abuse in the workplace: A preponderance of people willing to put themselves in other people's shoes, respecting and granting other people the dignity and respect that they expect themselves, and thereby acknowledging both the existence of the abuse and the scale of the abuse - how much worse it is than ramifications of the actions taken to preclude such abuse.
