You are right. Pfleger was left there way too long. He should have been defrocked years ago. He is a community organizer not a priest.
I don't think he teaches his congregation religious doctrine anywhere as often as social justice. They can tell you lots about gun control efforts, but if you ask any of them what the doctrine of the immaculate conception is, you'll draw blank stares. I've been on his facebook page and tried to discuss Catholic theology with them. The best you're gonna get is they will quote random bible stories or parables about Jesus to try and twist Pfather Pfleger into a Christ-like figure (funny, I don't recall Jesus ever telling the apostles to "snuff" the Samaritans, or that is Israel is the greatest sin against God.)
I agree Pflakey is pretty selective about what kind of "social justice" he preaches about too. As his parishioners will even admit, you never see him give sermons about all the women in his community having babies out of wedlock, or women using abortion instead of practicing safe sex.
