Hello Charlie "amalgame is a word of dentistery ,that mixed thing what is put in the hole of one tooth . Here with those Bobos we are pretty far from Health .Its a mental-salad-mix , they make with any ideas, concepts of living ,even in contradiction one with another .What is said is they don't care having together different point of views at the same time , that usally don't fit together .Different antagonistic choise .
The other :laissons/ means /let's passing by / don't care about ..
My explanation is may be not the best/easy ?!! Hope wou'll be on the way with someone else !
