Everyone has the same rights. We allowed the KKK to march in Skokie, and Maplethorpe and Serrano to exhibit their pornography and blasphemy. Liberal/progressive/socialist/communist...whatever they might be have the same rights to petition the government for redress of grievances, etc.
But they don't do so! The single legitimate approach they have to imposing gun control, censorship, warrantless searches, etc. would be to amend the U. S. Constitution. When is the last time you heard anyone suggesting that? No, they all demean the constitution as outdated, written by people using quill pens and ink, etc. But they don't have the integrity to suggest that changes be proposed and put before the people.
And that tells you everything you need to know about them.
