My ethos boils down to…

1. The Golden Rule: Your rights end where other’s rights begin, and vice versa.
2. Natural Rights: Any action or inaction, thought, or word, spoken or written, that does not cross the line of the Golden Rule is a natural right.
3. Ethics: All ethics are founded upon, and entirely dependent upon, points 1 & 2.
4. Morality Is Unethical: Morality, allowing for arbitrary precepts, is inherently unethical.
5. Effort: Strive to live ethically.
6. Inaction is Action: Inaction is, itself, an action. If your inaction results (even indirectly) in someone’s natural rights being infringed, your inaction is unethical.
7. Consideration: Actions often have cascading, indirect consequences, and you bear full responsibility for them. Therefore, failure to consider the indirect consequences of your (in)actions is also unethical.
8. Graciousness: Treat others the way they wish to be treated. Recognize the dividends that gracious behavior has on preserving the natural rights of both yourself and others.
9. Defend the Social Contract: Ethical behavior is a contract between individuals. Aggressors and instigators who violate that contract are not subject to its protections. As such, adherents are obliged to defend both themselves and others from such infringements to preserve the greater social stability.
10. Imperfection: Acknowledge that no body, no thing, and no system is perfect. Not you, not others, not nature, not these precepts. Mistakes are inevitable, it is the effort and intention that matters. Accept and treasure imperfection, and be faithful to the spirit rather than the letter.

Can you elaborate? The “Golden Mean Fallacy” is literally the name of a logical fallacy, though I don’t you meant it that way. Maybe a “things are more complicated than just black or white” kind of thing?

What you’re describing is groups of people sharing opinions that can differ with one another in good faith discussion.

The problem is, this is what fashies consider an “echo chamber”. The definition itself is not applied in good faith by certain cohorts. For example, people having good-faith debates are “liberal” echo chambers, because not toeing the alt-right fascist line is never considered to be good faith.

I’d suggest doing a little reading on what the political spectrum means, because they aren’t.

When you think a Siberian winter is normal spring weather, even ice cream seems warm.

My only problem with Proton is that they don’t work with native mail clients (especially mobile). I’d go with FastMail personally, but I do see the appeal of Proton.
