> You can do light meditation and even take an intellectual interest in the deeper teachings without seriously triggering anything.

Our fears can dominate our reality, and you are tritely recommending a possibly harmful path without knowing anything about them . . . like recommending eating a peanut to someone who knows they have a dangerous allergic reaction to peanuts. In the context of the article, your advice is especially egregious.

Please tread carefully in the world, effortless advice can cause long term harm.

Sometimes it is good to listen to our fears, sometimes not. Hard to judge others across the vast distance of a few sentences.

Of course. There is a world of difference between understanding something on an intellectual level and engaging in serious insight practice. Unlike insight meditation itself, there isn't really any evidence that the path I suggested is "possibly harmful".
