Shraga, you are partly right. I guess I shouldn’t tell others what strictures to put on themselves. So if someone wants to ignore the Jews they pass on shabbos that do not meet certain criteria, I can’t tell them they have to.
BUT
Do not for a minute think that such a choice of chumra is normative practice or demanded by halocho, or that someone who does not follow your chumra is transgressing. That would be pure unadulterated zealotry, to no useful purpose.
