Surely you see the socio-economic/racial injustice of this (?)
Wealthy nations, having created the conditions underlying global warming, are now responsible for a world which higher temperatures and extremes are now the norm, necessitating (in the minds of some priveledged societies) a broader use of deodarants.
But not all peoples and groups have access to the means to acquire the deodarants, and therein lies the inequality.
This will be an issue that comes to plague us and drive us further apart in the coming, so please pause for a second before you make a stink about others who, in your opinion, do not meet your standards regarding deodarant use.
