So if you acknowledge that the effects are real, why try to minimize it by saying its not real in any scientific way? Whats the point of that statement?Of course its effects are real. But it's not real in any scientific way.
Race may not be "real" but i know that my skin does not burn and peel like that of a Nordic. Race is a "social construct" but there are some key differences between the different races/ethnicities out here.
