I know that it signifies me as an Internet SJW by saying this, but I'll fuckin' say it: /b/ is an attractive nuisance

That statement makes you a thinking human being with a working brain; I hang out in 4chan and 8chan and I hate /b/. /b/ was always the shitpost containment board. /pol/ is a joke inside a comedy wrapped in the tragedy that there are people taking it seriously. (fun fact about /pol/? I know a Jewish guy who posts in there as a flaming neonazi. he thinks its hilarious and takes the bite out of the horror of racism. not sure I agree.) The tech boards like /v/ /g/ /sci/ all developed a culture that created a high cost of entry that kept out a lot of the undesirables. The thing about /b/ is that the goons descended into the board and used it to wage wars on each other.

4chan, and all the chan boards serve a purpose. Knowing what they are going in, and having the think skin and solid sense of "not giving a fuck" are the only requirements. Not everyone should go there. Hell there are people here I'd warn in loud, steady tones that they should avoid Chans.
