Masks aren’t without harm. My six year old sees a speech therapist, as do many in his class (those than can afford private sessions that is). His speech therapist says she’s never seen a cohort like his - she puts the amount of speech problems and their type down to them not seeing people’s mouths moving during speech.
Violet Affleck is of course entitled to wear a mask if she likes, and to encourage others to do so, and to raise awareness of their importance. Mandating their use is just nuts though. Her speech at the UN was garbled and rushed, so I doubt she was chosen for her public speaking skills.
I was also thinking MH problems or - I know this is so trite to say and I always roll my eyes when others suggest it out of nowhere - but possibly autism.
