There is no point, even my previous response was significantly downvoted, and that was quite constructive which contradicts your entire statement.
You might suggest such, but this has the effect of just baiting me for a response so it can be marked down more where you are engaging me for the effect to further punish.
You see these people don't do this because of their opinion, they do it because it causes psychological harm, its a totalitarian tactic that is not unknown. Silencing was used somewhat heavily during Hitler's rise to power.
Forcing the only conversation to first agree before moving forward, at any point, causes you to fight your own psychology to remain consistent and the process warps you subtly. Most aren't self-reflective enough to notice but the effect is the same regardless.
Robert Cialdini wrote quite a lot about the various lever of influences that are often used as mental compulsion/coercion, and Joost Meerloo and Robert Lifton both cover these structures and techniques in detail in the context of WW2 torture and moving forward. These behavioral structures run parallel with those of the Nazi's, and other totalitarian regimes.
This is what is happening, and when mild conversation causes this type of behavior, this is the time you should be most greatly concerned because its arbitrary, causes mass delusion, and continues until destruction, albeit slow, overtakes that group.
As far as I'm concerned, the people doing this can ride their train right to their own demise for all I care. They are true evil, and they'll be doing the world a favor when that happens. The rules of society will no longer protect them once they destroy society.
We were taught from children to not be violent. This is violence, there is no excuse for bullying, and people are no better than animals if they can't reason and be civil. What one does in small things, they do first in large things that matter.
If they want to be violent for a mild comment like that, they won't get anything from me, and I'll reciprocate in the only way I can right now, withdrawing and not providing anything of value.
I'll pray I never meet them in person because if you or anyone else tries to harm me, I'll be exacting an equal or greater cost in self-defense.
This destructive behavior is despicable on so many levels, and you say its not so bad but you don't realize just how bad it gets, this behavior promoting menticide, and robotization is what led to the gas chambers in Germany during WW2.
When no one questions rationally, or can express disagreement, evil flourishes. You can't ever argue with evil, you have to kill it, as we had to do during WW2 (at great cost).
Read the notes from the Wannasee Conference, or if you can't be bothered, rent Conspiracy (2001). The history is well documented by experts who studied these things to prevent it from ever happening again, and yet it seems no one has learned their lessons since they repeat it yet again.
They are emotional beings (/s), can you imagine that being a valid defense of Nazism during WW2? For the deaths of all those Jews in the camps? If it's unjustifiable at the extremes, it is unjustifiable anywhere.
These are the same things, the only difference is perspective and the fact that you don't have perfect information upfront at the bottom level, you only ever find out afterwards, and its a goose-step death march ever forward and people don't realize this is how it works. One step at a time, pivoting, with no questions.
This is only the beginning, and when you can't stop it early, then its too late to do anything later to prevent the massive destruction that these people inevitably bring on themselves and everyone else.
This is why it is so damn important to protect and maintain freedom of speech in a civil atmosphere. There can be no rational support for this behavior, not ever.
Please stop making excuses for the truly evil.
