Or that refusing to understand is a valid counterargument.

Way too many people think that if you explain something, you're endorsing it--even when you explicitly say that you do not endorse it. So frustrating, and it's a huge problem here on the fediverse.

Or that not vocally disagreeing is agreement.

On a related note, this is one of my favorite quotes: "It is the mark of an educated mind to be able to entertain a thought without accepting it." -Aristotle

Folks, you can understand why someone decided to kill themselves: e.g. a tragic life, and from their perspective, there's no one to support them, no one to love them, no one for them to love.

But it doesn't mean you agree with their decision to kill themselves.

If understanding = agreeing, a lot more people would be committing suicide while trying to understand why such a person would kill themselves. It makes no logical sense. Or it means that those alive is either of these: they either don't understand it out of naivety, or choose to not understand it to not kill themselves. Assuming it's an adult with their full faculty, who witnessed such a tragedy, that's just... such a sad world.

I'm not sure if its get what you mean.
