Oleg Tchernyshyov and "Sheikh" say that Homo sapiens are not members, ie elements, of the Animal Kingdom superset!

That is right- according to Oleg Tchernyshyov and "Sheikh, Homo sapiens are not members, ie elements of the Animal Kingdom superset.

Sorry but I can not explain why they say that.

All I can do is point out their "reasoning".

They have presented a set that contains a subset: {1,2,{3,4}}

That set contains 3 elements 1, 2 and {3,4}- (They do not understand that the element {3,4} contains elements 3 and 4 so they say that 3 and 4 are not elements of the larger set.)

Yet when one looks up a subset, we find:

In mathematics, especially in set theory, a set A is a subset of a set B if A is "contained" inside B. A and B may coincide. The relationship of one set being a subset of another is called inclusion or sometimes containment. Correspondingly, set B is a superset of A since all elements of A are also elements of B.

But anyway Homo sapiens are a subset deep inside of the Animal Kingdom superset.

Kingdom, Phylum, Class, Order, Family, Genus, species.

So by their "logic" Homo sapiens are not members of the Animal Kingdom because they are in a subset.

And these assholes are trying to teach me about set theory...
