What if I have a lot of friends? Is it now a pressure campaign?
What makes something telling the truth, and what makes something a campaign?
And, why do people so thoroughly fear the truth being told about them? Is that shame, or something else?
If you wish privacy, as we all do often, then stay private. Its easy and free.
But when your opinion is posted online and you willingly tie it to your real life identity, you cannot get canceled. No, in my mind, it's impossible.
You may cancel yourself. But people simply repeating your own words back to you is not a campaign, it's just a reminder of reality and truth.
