They have the freedom to say it, and I have to freedom to not hire them because of it.
Actions have consequences.
And I think you have serious misconceptions of the concept of "law". Here's an example - the CEO of Chick-Fil-A is very publicly anti gay, and anti gay marriage. He breaks no laws while expressing his opinions. However, people who don't agree with him have the option of protesting, boycotting, writing letters to the editor, saying mean things about him online, quitting their job at CFA, etc. People who agree with him can eat more chicken, protest the protestors, etc. No laws will be broken. Just because 100,000 people will never eat at CFA again (mob mentality) it's so far from a law, that you can't even see a law from there.
All of these things are part of free speech, and whenever CFA is mentioned, there will alway be a little bit of "oh, the anti-gay company" (whether spoken out loud or not). It's simply consequences (both good and bad) for his actions. I really don't see a difference here.
If we all thought that saying "we want to rape her with baseball bats" was an OK thing to do, we'd all laugh and say "boys will be boys" and nothing would happen. I'm certain that there are a lot of people in the US that think their behavior is acceptable and don't care about this issue.
However, there are many, many people who are tired of these kinds of attacks, as well as tired of men treating women like passive object for them to put their dicks in. I'm one of those people. These grown ass men know that it's wrong to say this shit, and did it anyway, in public. Now they have consequences to deal with. Not the law; consequences. You are welcome to be on either side of the issue, but my desire to see them pay a price is not a law.
I have a serious issue with one thing you're saying - "I don't even think that there are any "people like this" in our society."
Yes. Yes, there are "people like this" in our society. Put yourself in her shoes for just a moment. You are getting rape threats from unknown guys; you don't know who they are, where they live, or how serious they are. Scared? Feel threatened?
Our society, for too long, has turned the other cheek, and said "boys will be boys" when people do this. She was dressed that way. She had too much to drink. Why was she alone? Why didn't she fight back? How many men has she had sex with?
This is all bullshit, and it puts the burden of not being raped on women. Our mothers, sisters, wives, daughters, friends and neighbors. It's bullshit. Of course women should be smart, and limit exposure to risk (just like men do), but we need to get out of this cycle of blaming women for what happens to them, and expose the men who perpetuate these actions - whether they act on them or not.
