The difference is very clear. One is saying whatever you want to say under your own public identity or under a pseudonym. The other is pretending that someone else is saying something. It's not 'lying about your identity', that's a miscasting. It's pretending someone else is saying things that they are not. Free speech does not include fraudulently pretending that other people are saying things that they have not / would not say. Claiming that Free Speech must include this is intellectually dishonest and intellectually uninteresting as an argument.
