Help me understand this better. It seems like being blacklisted by a big company or even entire industry is bad, even life altering. But people get serious PTSD or sometimes even die from one single 5-minute fight with a cop.

Furthermore, I think shunning and blacklisting should be a protected form of individual choice. For example, I'm just not going to hang out with someone that's a racist. That is and should be 100% my choice. But I don't have a right to physically harm them. I'll argue that this arrangement of making violence special and different from harsh-words or shunning will make for a more functional society because we don't always all have to agree but we can still live in one place together.
