These stunts do some of us faded ones with family still in no favors either. While I'm fully out, it's a struggle to get family members to use critical thinking skills in all matters JW/WTS. Just when you think you've made some progress, they see crap like this, and it drives them back in further. It may not be a rational reaction on their part, but they're indoctrinated to fear opposers, so these stunts are counter productive when you get right down to it.
And similar to Simon's comment, and I've said it before as well - JWs have as much right to worship in their Kingdom Halls as do Baptists in their churches, Catholics in their churches, and Mormons in their places of worship. Singling out JWs for harassment is just sour grapes on an ex-member's part. The best revenge is living well, and leaving well enough alone.
