Hi, Warrener
I answered your similar question in another thread, then moved my post here when I saw this thread.
Sometimes 'unashamed' can be used to mean that someone supports something completely and outspokenly, without reservation, without considering possible problems arising from being extreme about a position. This may be the case here.
Personal opinion:
Free speech is wonderful, vital, and extremely powerful. But it can be abused badly. Free speech doesn't always mean that the speech is accurate or honest. It also doesn't mean that the speaker necessarily has any knowledge of what he/she is talking about! It can be viciously insulting and used for purely selfish purposes. It can be completely negative. It can be ranting, inciting, and geared toward promoting fear and hatred of one group for another. Etc.
Some people don't use free speech responsibly. A few people even specialize in using it irresponsibly. Some of them make a lot of money for this. ![Sad [:(]](/emoticons/emotion-6.gif)
