I really get the sensory overload objections, im the woman that walks into every room and asks for the lights to be turned off , that avoids my nearest supermarket because it is too loud, echo-y and overlit. I get it.
Jazz hands is sign language for applause that is only really useful when signing a performance that the viewer ISN'T at and cant SEE the audience. Eg signers on TV prog where the stage is filmed like the proms , Glastonbury etc
It is useless as a live expression of appreciation to the person on stage as they can't see the flipping audience. Useless in a lecture theatre or conference hall if the person commenting and receiving the applause/jazz hands has anyone sitting behind them, the wheelchair user WiLL be sitting at the front (fuck em eh ?NUS kids) Useless to those that have vision problems (fuck them too?) The truly noise sensitive won't be at opera, theatre, gig, festival .
Jazz hands is only useful when people are sitting in "the round" well lit, small group and hearing or not be otherwise able-bodied . Like the white, male, wealthy, educated tossers where when the NUS committee came up with this virtue signal.
I've been around woke wankers having these discussions for too many years. Pity me!
Phew feel better now...
