The 2016 convention had several talks that warned against associating with ANY who have become inactive, or faded..as well as "less spiritual ones" still in the congregation.
While it may be worded a little more 'in your face', the actual admonition is not really different from years past. They've always warned against associating with anyone who is 'weak' or 'less spiritual'.
That's not to say they aren't ramping up the rhetoric to instill (more) fear, but stripped down to its essence, it's the same basic tenant as always.
