As I said 4chan has always been about being counter culture. During early days 4chan was more liberal and Left leaning, then when government changed it switched. Had the Right held the office for longer 4chan would have again shifted more towards Left.
As for hacking and doxxing people you don't politically agree with just because of that, that sure wasn't the original "hacker known as 4chan" mentality. That was called "moralfagging" back in the day.
