I fail to see how this is at all relevant. We're not talking about flat-earthers (though messing with them is a glorious sport indeed).
I'm asking if you honestly think it's OK to call someone the 'worst mistake in human history" for acknowledging that some people think it's OK to break the rules to combat someone already breaking those rules.
If you do, then you are objectively a tyrannical person who only accepts their own views as truths. If not, then your meme was a hypocritical violation of your assumed-support of freedom to speak one's mind.
