Joffrey was a petulant child throwing a tantrum when he was screaming that shyt tryna make people believe he was the King just cuz he said it. His proclamation was one of disbelief. He couldn't believe that he would be challenged as the king. "I am the king! (Why aren't they listening to me?!)" That's what he was really saying. He was tryna reassure himself.
That's not the case with Viserys. He was speaking from a position of power, almost rhetorically, putting Brehlaryon and his powerful house in his place. Joffrey was throwing wild exclamation points, which are often unnecessary. Viserys dropped a calm period to punctuate his statement.
I didn’t proclaim them making the same statement from the same position. We agree
I think comparing that statement from Viserys to the statement from Joffrey is a little unfair. Joffrey meant it in a completely different way. He was trying to scare and intimidate and bully people. We haven't seen anything close to that type of behavior from Viserys.
Like I mentioned, Viserys has stepped his game up,
He’s just not perceived as flawless and powerful as it came across.
Otto, his right hand man felt COMFORTABLE enough to send his daughter for his own benefit and was successful gettin his daughter to birth the Kings child.
Otto felt COMFORTABLE being political tryna sell Raenerys them bum ass nikkas to be Viserys’ Kingsguard, instead of being loyal and choosing the BATTLE EXPERIENCED Kingsguard to fit the job of protecting the King’s life.
Raenerys peeped the bullshyt immediately, subtly called them out on it and chose Ser Criston Cole accordingly.
Corlys felt COMFORTABLE making a scene at the round table
Daemon felt COMFORTABLE throwing dirt on Raenerys name and telling Viserys he wanted to have her for himself.
Hell, Crab Feeder felt COMFORTABLE wreaking havoc in his land and Corlys had to tell him he was bein too SAWFT as the King to let that happen
So my point is, people are TOO COMFORTABLE playin with Viserys despite him being King.
Again, to Viserys credit, he stepped his game up.
He sent his army to Daemon.
Got rid of Otto (because of Raenerys, but still.)
I believe he’s a way more stable King than Daemon could ever be.
Overall Viserys is a stable good-hearted King, but to a fault.
His decision to marry Alicent, because he allowed himself to get played when his heart was vulnerable, is what caused the rift with his daughter, his HEIR to an extend.
I think the realm will see how good they had it with him if something were to happen.
