Thanks for the applause OP. One way to begin to stop 5G is with RF blocking paint and curtains... as in this video...

...from EMR Shielding Solutions. If we can make it hip and cool to raise shields in millions of homes... we begin to protect ourselves. It won't help birds and bees though so at the same time, we need to stop 5G antennas.

If RF blocking fabric becomes cheap enough, we could drop a sheet of it over any 5G antenna. I'm thinking comic-book scenarios right now to brainstorm. Maybe a drone with a retractable claw can be flown near the antenna with the claw and then it releases the fabric over the transceiver. Just a crazy thought. It would be a phenomenon similar to those people who insist on throwing a pair of running-shoes with shoelaces tied over power lines. Stupid move but basic idea is there for my idea.

Another idea to stop 5G is promote wired communications.

Another idea is to promote the research and buying of RF meters so we can all measure what we're being exposed to in various areas. We can promote the idea of talking about it in a way that is non-offensive. Like "I'd like to meet you at that coffee shop but it's too 5G-hot for me-- let's meet somewhere else".
