Quote from Wiki,
Most scented candles contain paraffin wax, which is derived from petroleum, coal or shale oil. When it's burnt, paraffin wax releases toxic compounds into the air, including acetone, benzene, and toluene – all known carcinogens. So not only are they damaging the environment but our health, too.
So, the idiot wokey brigade after all that fuss over second hand smoke (Which is possibly harmless) are quite content to fill the air with carcinogens.
Do left wingers ever think, or do they simply emote?
