Me telling someone to go fuck themselves probably isn’t a problem, but me telling someone with learning difficulties to go fuck themselves and them feeling compelled to do it and hurting themselves probably is a problem.
technically yes, but attempting a crime is often considered a crime itself.
"The only remedy until the removal of the Zionist regime is firm, armed resistance."

"We will support and assist any nation or any group anywhere who opposes and fights the Zionist regime."
Now compare that to the Trump tweets that prompted his suspension, according to the Twitter statement:
"The 75,000,000 great American Patriots who voted for me, AMERICA FIRST, and MAKE AMERICA GREAT AGAIN, will have a GIANT VOICE long into the future. They will not be disrespected or treated unfairly in any way, shape or form!!!"
"To all of those who have asked, I will not be going to the Inauguration on January 20th."
To claim that the second set of Tweets incites violence more than the first is absurd. Yes, context matters, but it also matters for the Ayatollah tweets. When the leader of Iran advocates "armed resistance" to the state of Israel, we know exactly what that means.
He tweeted praise for the rioters and justified the riot while the riot to stop the constitutional process of the peaceful transfer of power was in progress.
So in this case he might be technically correct in identifying the exact people he opposes... Possibly.
Iran is a bit weird, they actually have a seat of parliament reserved for a Jewish representative. See here for details of the current holder of this seat: https://en.wikipedia.org/wiki/Maurice_Motamed
Twitter overtly adopted rules granting high government officials this preferential treatment to justify not acting on the many complaints of Trump's flagrant violation of what were previously nominally universally applicable rules on the platform at the outset of his term.
So, yes, Khamenei gets preferential treatment compared to the average user (as did Trump); that's the overt policy.
Trump on the other hand has clearly demonstrated his ability to incite action.
But one might reasonably argue that people who don’t follow certain ideologies get reported and suspended more often.
