First, although I don’t really feel it was my place to do it, I offer an apology to those who were pestered by repeat callers who had specifically asked Witnesses, or any other specific callers, not to return. Nobody likes people who can’t take an explicit hint. Implicit hints are not the kind of thing that put an obligation of courtesy on a possible caller. (I know that if someone specifically told ME not to return, I would not.)
As for Ciudad Juárez, I am certainly not ignorant about the strife and danger in Mexico that has prevailed there in the last ten years or so. As a paralegal I have, more than once, prepared documents for an attorney defending a client who did not want to be deported to Mexico, for obvious reasons (and finding good solid American law in support of his argument). I merely did not know that that city was the worst offender.
I agree with you about those street evangelists who approach you on the street and ask, “Are you saved?” I would pause and say, “That’s bad if you’re wondering too.” Then I would walk away. That’s easier for me, I admit; as big and husky as I am, most people take one* look* at me and, IMO, conclude that that I could be dangerous if I became violent. I rarely do–I like to consider myself a gentle giant and don’t go around scaring people, but, hey, I use what resources I have when I think someone is too adhesive for my taste.
Opt-in/out; Bouncing Betty; toe-poppers…I’d appreciate it if you would give me definitions for these words. Thanks. 
Am I playing word games? Here’s the entire entry for “solicit” in my Random House Dictionary:
so-lic-it [phonetic spelling follows], v., -=it-ed, -it-ing. –v.t. 1. to try to obtain by earnest plea or application: to solicid aid. 2. to entreat; petition; to solicit the committee for funds. 3. to seek to influence or incite to action, esp[ecially] unlawful or wrong action [commission of a murder, for example–D. M.] 4. to offer to have sex with in exchange for money.* --v.i.* 5. to make a petition or request for something desired.** 6.** to solicit orders or trade: No soliciting allowed in this building. 7. To offer to have sex fior money. [1400-50; late ME <MF* solliciter* <L sollicitare to exicte, agitate, der. of sollicitus troubled (soll(us) whole + -i- -I-+* citus,* ptp. of ciere to arouse)]
As for that sign “NO LURING ME INTO EVIL,” the Witnesses probably quit coming because they decided that the attitude that created that message was not one worth bothering about.–Matthew 10:14.
