It's incredible how we are now destroying free speech because we are so afraid of hurting someones feelings.
Some day when you go to school or get a job you will realize that for most of us the US Constitution is irrelevant when it comes to our day to day behavior. Regardless of what is written on a piece of paper in Washington DC there are tons of perfectly legal reasons I could get fired. By the time you are pulling out the Constitution to defend what you are doing you've crossed dozens of lines already.
First off, I both work and study, so take your condescending tone somewhere else. Secondly, there is no logic in justifying wrong with other wrong, sorry.
