Not my forum, of course, but that’s absolute nonsense. If one requires validation before one can speak then one is ceding one’s right to be heard at all. That’s your choice, certainly. But don’t use it as an excuse to dodge an issue.
It’s pithy, I know, but I’ve long been fond of the saying, “If you take what they give you, you get what you deserve.”
You want to effect change? You want to see new paradigms? Speak loudly and firmly. No one can give you the authority to be self-actualized and possess your own agency. Only you can do that. If you choose not to, then fine. That’s your call and I’ll support you in it. But don’t tell me you need someone else’s permission to speak.
