are usually not regarded as authoritarian

Despite two of the primary liberal countries, the US and UK, genociding entire continents.

The liberal political system of bourgeios "democracy" is a much more effective system at genocide than even fascist governments.

This keeps coming up in different threads - I hope you'll receive the following as useful, and not combative. I occasionally get to feeling grumpy and dunky but this isn't a long subtle road toward that.

You have a somewhat unique and actually beautiful opportunity here ("here" meaning Lemmy in general, and this specific thread) - one that is hard to find elsewhere, at any rate.

There are well-educated people (obvs not everyone) with very different learned and lived POVs from yours, here. And there is an asymmetry that you're either missing or denying. These folks who you think you might need to educate about western / US flavored liberalism? They have heard what you're saying, considered those ideas in a broader context than you have, and rejected those interpretations. It isn't some missed knowledge you're sharing like you imagine, or some correction you're making to someone else's limited understanding.

You're missing this, and I really want you to not, for your benefit first, but for all of us - it truly is you, in this case, who has much to learn and little to teach.

Don't shut that personal growth out by being defensive, it doesn't lead anywhere. It leads to intellectual death, the ending of internal development, a death sadder than the final one. There's much to learn and you have a truly golden opportunity to do so, here.

Start with just asking yourself "what if I'm wrong? I'm probably not, that's the most likely outcome, but what if? What brain doors open when I try to find out?"

[Edit: to put a finer point on this attempt, I can remember enough of how I used to be "you", hence the unremarked assumptions about you I made throughout. If being "correct" matters, it simply can't be done with only the info you're allowing in at the moment. Best wishes.]
