Do you think the “old west” in America was actually like a western movie? Like, have you played red dead redemption and think that’s just how every day actually was? That fucking hilarious. Also those “social consequences” kinda prove the other guys point. You’ll be ostracised because other people have empathy and look down/ostracise those who participate in immoral behaviour because they know it’s wrong.
This, this also plays into the age-old debates about intolerance of intolerance and “free” speech. “Free” speech means that you are free to say whatever you would like, as long as you are willing to accept the natural consequences, and tolerance is one of many other social contracts we have in place.
You are welcome to lie to someone, to call them names, to tell them awful things or to just spout bullshit all day. But the flip side of that is that people are also free to say what they will, and engage with who they want, and if you are a real asshole who finds issue with everyone very few people will willingly do so with you. In other words: don’t poke the bear, and you won’t get eaten.
