Why do american liberals equate everything to sex? It looks like every relationship between two people must be of a sexual nature to their perverted minds

>guys hugging each other
>dad kissing his daughter
>any peck/kiss on cheek or forehead
>children siblings bathing together

all of these are uncommon in the united states of shartmart

Why are americans so fucking abnormal, why are they prudish at first, but then liken everything to sex when they see european relationship habits?
