Sectarian bigotry is still common. In fact, bigotry in general is still common. What has changed is the self-righteousness and the change in focus onto groups that "deserve it" (i.e. the English, Jews to name two of the most common...not including sectarian obv, as that is just so prevalent).

And I know someone who used to work as a diversity officer (they ran seminars on diversity) for the Police: bigotry runs very deep unf. The slightly bizarre twist recently is that the Police now spends a lot of time on hate crime (i.e. chasing easy arrests on Twitter)...poacher turn gamekeeper I suppose (and again, the self-righteousness is utterly incomprehensible).
