>>13852338/pol/ attracted a shitton of low IQ people during the 2016 election. Reddit, /r/the_donald, they are just one of these places. 2016 is when /pol/ became universally known in every corner of the internet, thanks to the general rise of the right due to the refugee crisis among other things. And before that moot cucked out and that led to a mass-exodus of /pol/fags to cripplechan so the gap was basically filled with newfags from reddit.
Btw, old /pol/ hated newfags too if you know. Nobody pretended to be from 2003 but there wasn't any of the cancerous "4chan culture sux anyway so I'm allowed to be an utter faggot" like you display 24/7.
