These sensitive members of the community are going to grow up, so I look forward to seeing the crowds watching Aussie rules football wriggling silently in their seats...
Here in the UK, the sensitive souls get ear defenders.
One does wonder how these snowflakes will cope in the real world when they grow up. The first thing that will happen is that they will fail at something - not get the job to which they naturally assumed entitlement, get binned (obviously in a caring and non-judgemental way) by their racially diverse and sexually ambivalent partner, or struggle to come to terms with the emotional turmoil of losing a recently deceased, dearly loved celebrity.
It's all going to be a bit of a shock. However, it ain't Facebook any more, so fekkem!
Our school tried that silent clap thing 30 odd years ago, basically do the clapping motion but "pull the punch" at the end so the hands touch but without making noise.
250 kids sitting with arms folded looking exasperated when we were supposed to "clap" got the point across and normal clapping was ordered to be resumed, which obviously was when most people decided to do the silent clap thing.
