Do liberals believe in the Constitution?

Well we all know they don't believe in the 2nd amendment. I think they only believe in the 1st if its speech they agree with. I've noticed that if they don't agree with you they result to name calling such as: racist, bigot, ist, , ignorant, war monger, and redneck. They also want to eliminate talk radio. Now i may not agree with everything msnbc says but i agree with their right to say it. When is the last time you heard a liberal say that.
