Very true!

There is certainly some room for discretion when it comes to folks who are actively belligerent, drunk, high, or otherwise presenting themselves in a way that would be an undue distraction for those who came to worship.

But this comes down to recognizing the purpose of Sunday worship. It is not for public outreach. It is for the saints to worship their God as he has called them to, and to fellowship with and build one another up.

When doing outreach ministry, one should absolutely expect to encounter folks of all stripes, and probably keep the young children at home with a babysitter.
