Roger went out of his way to go beat WB for no reason, nothing like Luffy
You're claiming Luffy doesn't love to fight for fun? Yeah, that's why both he and Zoro were tempted to fight Jesus Burgess the first time they saw him just because he was claiming to be strong (but didn't because they promised Nami not to fight). "Nothing like Luffy".
Also, if you're referring to the latest flashback, it's the WB pirates who headed over to the island where Roger was, not the other way around. Roger was excited to think about fighting a samurai because he had never met one, but it was the WB's and Oden who went for a fight.
Garp said Roger would go looking for fight and would never stop until defeating his enemies, nothing like Luffy
Garp told us that Roger would destroy nations and once massacred an army of a nation because they said something bad about 1 of his nakama, again nothing like Luffy
I already argued back at this claim but I'll do it once more. Last time.
Those are just Garp's contextless quotes.
Luffy has had one to ten fights in EVERY SINGLE ISLAND he's stopped at, and he fought the government in some of them. If someone from the world of One Piece was to follow his carreer (which isn't the same as reading his adventures on the manga as we do) Luffy would seem like a wild beast looking for a fight at every island he stops at, and hes toppled kingdoms' before (like Drum). Quote his exploits so far with no context, from the mouth of a marine, even a marine like Smoker, and Luffy will look like a bad guy. So far Coby's the only one marine who would actually speak well of Luffy.
Once again. Germa 66 is a kingdom. Luffy would be willing to destroy it if they messed with Sanji, just like he "destroyed Arlong Park because they made Nami cry" or destroyed the Baroque Works "because they made Vivi cry".
Was there much more behind it? Yes, but that's something we the readers know.
We have been shown Roger on many flashback and you weren't able to defend your previous statement of "Roger has been shown as bloodlust and always looking for a fight on flashbacks". Flashbacks, as directly read by us, are what tell us for real how Roger's character was, not Garp's words, and Roger in flashbacks acts consistently just like Luffy does.
The statements Garp made are pretty solid prove since he is trust worthy and would never say BS just because.
Garp hates pirates. That's all there is to it. I still haven't seen a single flashback that proves Garp's words about Roger and until there's one that's just some biased talk from him fearing pirates ("fearing how someone that powerful doesn't follow the law").
Shanks and Luffy would never fight or kill anyone because they said something bad about their nakama, the bar scene with Higuma and Bellamy should make this pretty clear that both of them are not like Roger.
The bar scene with Higuma was about Higuma laughing at Shanks, not at his crewmates. He actually started killing them as soon as they started messing with Luffy.
The bar scene with Bellamy was about upholding the promise made to Nami.
What similarities though, you have only being questioning me but you have never said this and that are like Luffy and so and so said Luffy and roger are similar because of 1,2,3. The only connections are about being a D. and Pirate King nothing else!
I don't know if you're serious now because I have mentioned more than one parallelism along these posts. Their attitude in flashbacks is consistently the same. How they treat their nakamas and their rivals is the same. How Luffy recruited Zoro and how Roger recruited Rayleigh is the same (did you miss my post mentioning all of his flashbacks? None of which show some bloodlusted fiend).
I don't know what else to tell you, since we aren't agreeing on a fundamental level on Roger's personality (the way I see it: mostly because you're placing Garp's vocal opinion on the PK as "factier" than flashbacks) and this isn't even a talk about power levels, so I think we should drop it as it is.
