This brings back memories of my being set upon by some older worldly childhood peers who pushed me off my bicycle when I was doing my magazine route as a kid of maybe 8 or 9. I ended up with grazed knees and a bleeding lip. Awake magazines were strewn over the grass verge. A nice Catholic lady rescued me, phoned my mother who came and picked up me up and for a good few weeks the local congregation used my brave example as proof that our organization was the truth.
I am against any form of publically harassing Witnesses going about their lawful activities. I do not find it funny - even if there is no claimed intent to carry out sundry acts against these basically law-abiding and unobjectionable people. The OP comes across as just another OTT instance of bullying.
