When the Jehovah’s Witnesses show up at my door I tell them that I love Jehovah and thank them for coming. Why would any decent person be mean to them?
One of the sister missionaries from my Ward told about when she was in Germany and an evil person dumped a bucket of water on her. These kind of things only serve to strengthen our testimonies and resolve to love our Savior more and serve Him with all of our heart, soul, mind and strength.
Now who's being "judgemental"?
