It is awkward to defend free speech. That's why nobody does it. It is a good idea in theory, but who is going to defend it?
Terrible, awful, horrible, disgusting, filthy, rotten, distasteful, and repugnant speech is the only type of speech that needs any protection. So basically if you defend free speech to the average ignoramus it appears you are defending what the speaker said and they ignore the fact that you are fighting for free speech. Let's just agree that the founding fathers were using some mild hallucinogenic medications when writing the constitution.
The 2nd amendment, the 3rd amendment, and the 4th amendment are even more unrealistic than the 1st amendment. It took me 43 years to realize this. I used to live in the United States of America. Now I live in reality under the rule of cruel humans who run the legal entity named, "The United States of America". I wish America existed but it simply doesn't. Reality hits you hard. The constitution is not respected by those in power. Those in power have to appease the masses. The masses are dumb as dirt and hate American principles.
