I won't go into details, because I am doing JK research for you. But again, No, you cannot have any opinion you want. You can't believe that Jews or Black people or any group is less than and allow it. It's not about "hurt feelings", it's about people's lives.
You literally can. I or anybody else can have whatever opinion we want and there’s nothing you, the government or anybody can do to stop that. It’s impossible to police opinions, at best you can prevent certain ones from being discussed in a public space but that won’t stop people from having the opinions.
It literally is about hurt feelings, opinions don’t impact people’s lives, they hurt people’s feelings and we live in a society now where you will get backlash if you say something that hurts certain people’s feelings.
We will never agree on this which is fine, but I’ll end with this. The goal should be to change someone’s mind, not punish them or try to dictate what opinions and beliefs are allowed. That is an impossible task and will only lead to more conflict.
