What if 4chan never existed?

You comparison still makes no sense whatsoever at all bro. You can edit my post all you want but it doesn't change the fact that saying Adolf wouldn't exist without Alois Hitler is different from saying 4Chan wouldn't exist without 2Chan. Plus the fact that Adolf indeed would have never been born without Alois so it actually backs up the claim that 4Chan wouldn't have existed without 2Chan.

4Chan needed 2Chan to exist.
Adolf needed Alois to exist.
Southperry needed Sleepywood to exist.
Sleepywood needed MapleStory to exist.

So how the pineapple does that make the argument invalid?
