The enneagram institute's descriptions seem terrible in that they mention how self-controlled the 1 is, but 1s aren't self-controlled in emotional expression or anger like 8s are and history is full of 1s and 2s who murdered their spouses or beat their children uncontrollably. 8s are always in control of their emotions, just not going after what makes them happy or gives them control or relief and they're not listed as gentle when they are more gentle than most types and they aren't fragile inside or hurt like the description on the enneagram institute website says; they don't snap and hit a child, yet 1s and 2s do. 8s also, in some cases, are not authoritarian as leaders; type 8w7 Trump sx/so is far less authoritarian in policy (especially war), far more cautious, far more gentle, far less blunt, far more supportive of due process, reciprocal justice, and respectful of international boundaries and human rights and presuming of innocence and far more objective, than 1w2 so/sp Hillary Clinton would've been. Trump requires more loyalty towards himself, but he's a lot more fair, rational, and restrained and indecisive (which is good) than Hillary Clinton would've been. As narcissistic as he seems to some people, he's totally misunderstood (he's joking, and his rape accusers were lying, Kobe Bryant's accuser wasn't). He and/or his image is also both the victim and beneficiary of so many people jumping onto social bandwagons (popular movements). He knows the difference between extreme right and extreme wrong and is more likely to never go with extreme wrong like Hillary Clinton did. Which brings you back to 8w7 sx/so having higher self-control than 1w2 because the 8w7 sx/so can more easily say no and refuse to defend guilty people than the 1w2 can, the 1w2 technically isn't self-controlled but rather other-controlled. Also, Trump has married women who were not very emotional and who were independent and who could stand up to him (or others), so he actually didn't subscribe to gender norms.
Also, I think the ILE-Ti is the poster child for 8 sx/so, while 8 doesn't really fit LIEs; LIEs are anxious and needy and emotional but don't realize their anxiety. 8s are more self-aware than most other types, especially 1s; ILE-Ti are highly self-aware. 8s really aren't that blunt or that loud (they're not angry, they just want control and they know how to get it so it's unlikely for them to be rapists), that's more of a 1w2, 3, and 6 thing in my experience (1w2, 2, and 3 and so/sp more likely to be rapists than 6 and 8 and sx/so).
