1. No, the Forum member in post #22 set the "harmful" bar. His declaration was "hate-speech is harmful."
And thus it's the bar for the claim or counter claim you made
I pointed out the difference between real "harm" and personal offense. In your examples the speech is actually an action, a purposeful lie with the intent to cause immediate harm.
Some speech is an action and some is not? What a tangled web you weave.
And real harm vs personal offense...sounds mystical!
2. No, I don't buy your "psychological harm" argument. It is too broadly applied, and serves to justify all those who argue "hate speech" is harmful.
You don't like it, therefore it's not true? Sounds wise.
IMO argument's like yours justifying these kinds of reaction signals to "psychological harm" is part of the problem we are seeing these days with all these "safe space" seeking, easily offended, closed-minded, and clearly intolerant members of our more recent generations.
Like the conservatives at twitter who need a safe space to talk about their conservative nuttery? Why are those snowflakes crying? Were they too made weak by the SJWs who they profess to hate? Funny.
IMO your "psychobabble" ideology is weakening them mentally, making them more susceptible to mental distress and childish reactions.
Which psychobabble ideology? That people can say hurtful things to one another? That's just a fact.
That for some it's lasting harm? That's a fact too.
What's more important is for fine people like white nationalists...who champion not just hate speech, but hate speech to motivate people to join their cause, to support government/candidates like Trump and others who dog whistle to them, and who have a long history of violence (KKK, Ayran brotherhood, etc.), and specifically believe citiznes in the U.S. should leave because of their hate beliefs. Or hating on Muslims, which leads to Muslims bans, or an Indian guy getting shot because some redneck thought they were a Muslim.
Speech can be better described as a tool. Tools can be used for bad, or good. Admit it, and move on. This constantly denial of reality that conservatives/libertarians do, looks exhausting.
POS uses speech to make a living. Some people use speech to teach the next generation. Some use it to build bombs that killed U.S. citizens.
Some use it to foment violence. Some to quell violence. See how reality works? No tangled webs that on casual examination, are shown to be absurd.
