Yeah no need to make some grand statement about wearing one...just like no need to make some grand statement about not wearing one. Just wear one (properly) and go about your day. IMO the more we normalize it by not making it such a divisive thing the more people will jump on to doing it.
With respects to my experience I haven't seen too much success stories on people using preaching either extremes (the personal freedom bunch or the
for wearing one and you're awful for not bunch). I've seen more compliance when people around you show you can do normal tasks with it on, that it's no big deal by virtue of wearing one (because wearing one can still create uncomfortableness) because it has become a habit and really in a nutshell leading by example in the visual front.
