> Another person points out that even if you hate 4chan (or especially if you do), it'd be better left intact to contain the culture that foments there. Otherwise we might see /r/The_Donald style posts all over the internet.

That you are pointing to a subreddit as an example of the problem that might exist elsewhere in the internet if 4chan doesn't survive to "contain the culture that foments there" would seem to indicate that 4chan does not, in fact, effectively contain that culture now.

Containment seems almost fractal to me. /pol/ drains other boards of people who complain about black people and Jews all the time and also drains the nastier sorts out of /r/The_Donald.

/r/The_Donald, in turn, drains Trump fans from /r/politics and the like.

Of course, containment isn't perfect.
