I suppose it's possible to infer that Black and Latino folks in the US tend to be lower-income and thus they tend to live in smaller homes (more inhabitants per sqft) and perhaps thus have worse indoor air quality overall compared to their White or Asian counterparts.
But yeah, I still don't think it's necessary to bring race into it. If your science holds up and gas stoves are significantly linked to childhood asthma, you've got a good argument for phasing them out. If the science doesn't hold up, then you don't.
But the low income housing is also typically more drafty too, isn't it? So that would lead me to believe that there would be less indoor pollution built up from the range. Unless it is turned on for heating purposes (i.e., boiling a pot of water to get humidity in the air, etc).
