What Exactly Does Freedom of Speech Mean?

Freedom of speech, the first amendment to America's constitution. The legal definition of freedom of speech is;

The right, guaranteed by the first amendment of the U.S. constitution, to express beliefs and ideas without unwarranted government restriction.

So once more, this amendment protects you from government censorship. You cannot be told that you legally are not allowed to say certain things, with the exception of inducing unnecessary panic, such as shouting "FIRE!" in a full movie theater when there is not in fact a fire. But I am really sick and tired of people using that right as a shield.

"In regards to Zendaya's dreadlocks, I feel like she smells like patchouli oil or weed"
"That was really racist Giulliana Rancic, black women should be proud of their natural hair."

"Bruce Jenner is a science experiment, we should be focusing on real news."
"That was really transphobic Snoop Dogg, it's Caitlyn, and she is finally being who she really is."

"The German futbol players let Norway score they goal because they didn't want to mess up their hair."
"That was really sexist Stephen Smith, it was a good shot and if a man did poorly in a game you would just attribute it to how he played."

"When guys whisper in each others ears I always think it's kinda homo."
"That was really homophobic Iggy Azalea, there is nothing gay about nonsexual and nonromantic acts between same sex individuals."

"FREEDOM OF SPEECH."

Freedom of speech protects you against government censorship. It does not mean you get to be an asshole and everyone around you just has to allow it and say nothing because "freedom of speech." If you say something awful, people are going to call you on it, and they should. There is no law that will protect you from criticism or having to own the things you say. If you tell me that I can't do something because I am a woman, you are legally not going to be up against any sort of problems. You won't get sued and you won't go to jail. However I hope every living human within earshot tells you that sexism isn't funny. If you poke fun at the gay guy at work, freedom of speech will not protect your job. That could be considered harassment. You could get penalties at work or even lose your job entirely. Freedom of speech doesn't make you invincible, it simply protects you from government censorship.

I would like to make it known that none of the people who made the above comment actually used freedom of speech to excuse their deplorable behavior, I just wanted real life examples of offensive comments that we would all be familiar with to tack on that excuse we hear so often.
