Is there no way to stop these garbage liberal posts?

No, there is no way to stop any text-only post to rec.woodworking that
does not violate the terms of service set out by the poster's internet
provider because rec.woodworking is not a moderated group.

Binary posts, however, will be dropped by most news hosts automatically.

Use a decent newsreader and learn to filter. If you insist on using
Google Groups, though, you'll need to learn how to simply ignore posts
and threads that offend your sensibilities.
