It certainly applies here, but if the words written with the key board would draw a likely violent reply if uttered in person, then it is not proper speech as your quote illustrates.
Peruse the posters assertions of a directly personal nature and you will see that. If you don't then you are using the quote as justification for personal attacks to cover a lack of knowledge on the subject matter and what can only be identified as salacious and specious argument to elicit a anger response.
In other words.......trolling....
In other words, ou were not only practicing the "free speech for me and none for thee" so prized by the liberal crowd, you have now said that anyone who expresses those opinions should not only shut up, but should expect a beat down. Truly, a mark of real intellectual prowess.
I suggest you quit whining. This is FR, so man up a little.
