I don't think anyone should do anything...

I think you should instead seek to understand her...

I see this all the time: 'There's no right or wrong, everything just is. Anyway, stop talking smack that's so messed-up!'

Just because non-duality removes black and white doesn't mean people stop reasoning about ethical issues. So when you tell someone that they're not entitled to their opinion on the grounds that non-duality exists as a perspective, then your own logic deflates the force of your conventional-sounding claims that follow that ground-introduction.

Ethicists for a long time have realized that what they're talking about isn't chemistry where they can point to a table of elements, 'See this is H-2-O.'

Granted this, when ethicists talk about 'right' and 'wrong' each isn't talking with the assumption that they know everything or that all things are either black or white, nor does ethics need to be precise like chemistry in order to be of value.

Reasoned discussions can happen about events or actions that have moral overtones, and some peoples' suffering or insight changes because of exposure to that, and therefore those people see some value in conversations about ethics and events or phenomena that employ the notions common to ethics.

I think you dishonor her memory by calling her actions damaging

By your 'non-dual' view, this author and their opinion and their work are also just phenomena appearing in your nature-of-mind, each exiting tracelessly as it had entered awareness. Nothing more nothing less.

They simply are. She simply was. The author's article just was.

OR you can accept that reasoned conversations can happen about ethical matters and events, so then we can proceed — but at the price of you criticizing another for having an opinion or accusing them of 'dishonor' because they had a disagreeable view of an event that touched on ethics.
