Purity gives freedom from any unwanted control. Something controls you if you can't resist reacting to it. If you can resist, you create yourself a new option that wasn't there before. And having options that let you decide according to your own preferences - is freedom.

Visceral reaction to unwanted control can happen in one of the 3 ways:

If any explicit reaction can be provoked repeatedly and indefinitely, that's addiction.

To heal the damage caused by addiction, one first needs to learn other ways to react to something, as an exercise meant to change focus voluntarily, to regain control on one's own attention.

Then, one needs to unlearn any visceral reaction to external factors (macrocosm events, facts of objective reality), both negative and positive.

Third step is withholding explicit reaction to one's own internal events (microcosm, subjective reality), while still acknowledging their existence.

Ability not to react to something involuntarily is not to be confused with any kind of law or ban. Reaction is not forbidden, it just should not be mindless and unwanted. Which takes a lot of time and effort, but the result of the success overcomes initial hopes.

If a phenomenon doesn't vanish from lack of reaction, it means it has passed a validity check, and it is therefore not a whim or a fantasy. At this point it is worth considering on its merits, in its own terms, in good faith.

Positive approach to things that feel weird is counter-intuitive, and it's a common human habit to be suspicious by default. Indeed, one should not give trust and hope to something unverified. But if it has been thoroughly verified, it won't go away and needs proper care.

Which, again, does not mean visceral acceptance. Work needs to be done to design terms of productive communication with a given phenomenon. Requirements and rights need to be built, gradually, thoroughly. And for that, all the verified aspects need to be heard out and acknowledged.

Terms freely and openly designed in that manner will be future-proof, and new factors of reality won't dethrone them on principle, because they are already fair. Awareness of fundamental differences - in states of one's mind, as well as in different groups of people - will naturally lead to balance, as long as neither side is taken blindly.

That allows society to work together, tolerating each other's weirdness in behalf of common self-actualization. And if each human aspect is taken with empathy, there will be no reason for radicalization, because the latter is just a result of unnatural alienation and oppression.
