Writing off an entire facet of life as toxic, is toxic.
Anything taken to extreme can be harmful, but some of the most grounded and successful (as in, living well) people I know are those with a self-aware religious foundation to lean on. People may bring up examples of religious cults as a reason to discard all religion, but surely the same could be said for the many secular cults. We shouldn't throw out the baby with the bathwater, as they say.
