What if 4chan never existed?

Lol, that makes abso-f'ucking-lutely no sense.

"What would the world be like without Hitler?"
"Adolf Hitler exists because of Alois Hitler. This thread is now invalid."

"What would the world be like without the internet?"
"The internet exists because of ARPANET. This thread is now invalid."

What you said makes abso-f'ucking-lutely no sense at all. What you're comparing is completely different and unrelated bro. If you don't want 4Chan to exist you would have to take out 2Chan first since if 2Chan never existed 4Chan would have never been made.
