Well, say person X thinks we should have fewer H1-B visas. Person Y thinks to themselves "Hey, this is my enemy! He is trying to expel me from the country! He's attacking me! He makes me feel unsafe" And all of a sudden, you can claim to be firing people for being abusive, when in reality you are firing someone for expressing their policy preferences. And if we really want to have open debate, we need to discuss these things. Imagine if you are pro raising capital gains taxes, or repealing Prop 13, and someone else depends on that for their livelihood. They will feel personally threatened. Or someone who is pro-life might make someone who is pro-choice feel personally threatened. And I haven't even gotten into foreign policy. In this modern era where everyone is screaming about being "unsafe" whenever they hear something that they oppose, and everything is personalized, pretty much everything that you feel strongly about is going to sound abusive to you if you are on the other side.
