Silencers re legal & about to be available over the counter without the $200 tax stamp soon when the HPA hearing protection passes. In many gun unfriendly countries silencers are over the counter hearing protection as it should be. Michigan is legal to own & hunt with silencers & some are under $100 & it's legal to build your own but don't start building till the tax stamp is back or HPA passes. The key is subsonic (below 1100fps) so no sonic crack. A 22 rifle all you hear is the hammer click the firing pin & of course what you hit.
You can lead people to knowledge but you can't make them think.
