It costs only a few dollars and a little time to become an activist. My local Ace Hardware store sells spray-on adhesive for a little less than $5. I used my laser printer to print out the following page:

I cut out the labels and put them in my pocket. Then, as I walked toward my Back the Blue rally, I pulled them out, one at a time, and pasted them to utility poles and other suitable surfaces using the spray. Here’s a “suitable surface:”

I think the rain will eventually wash it off; it’s not permanent. Here are some tips that y’all can learn from my experience:
Keep the labels in a plastic bag, not directly in your pocket.
Wear latex/nitrile gloves.
Use tweezers to pull the labels from the bag, and a toothbrush, or something similar, to spread the glue around.
I didn’t do any of those things – and I got glue on my clothes and all over my hands; it was difficult to get off. Some of the labels became unusable because they folded over and got glued together. It’s a learning experience, but I was able to plaster a few of them in downtown Portland.
Next time, I’ll make the labels a little bigger.
Please join me in this effort, and let’s stand with our beleaguered brothers and sisters in South Africa.
Study Arabic Afrikaans. Arabic Afrikaans is a variety of Netherlandic spoken by Muslim Malays written in the Arabic “alphabet”.
Very interesting, and I’ll look it up. Why did you put Arabic “alphabet” in quotation marks?
Because Arabic doesn’t express all vowels by default, making it technically an abjad.
Of course.
Why not just print using peel-off sticky labels that already have the adhesive built in? Adding glue yourself sounds a bit crazy.
That was my first idea. There are two problems with that. Firstly, it’s too easy to remove such stickers, and secondly, they’re very expensive to purchase.
Here comes the FBI
It would be funny if I got visited by the FBI for putting up stickers… but not surprising.
