etiquette question - was I in the wrong?

I've been surfing regularly for not quite four years, mostly on a 9'6" performance mal. I get out 1-2 times a week year round, and while I'm by no means hot s***, I can control the board and feel comfortable in slightly overhead surf so long as it isn't too steep and hollow. Also, I like to think I have a handle on the rules of etiquette.
So here's the scenario: today I was surfing at a Victorian break mostly frequented by longboarders. Clean, 3ft lines, and with the summer sun, the crowds were out. I paddle into a head-high A-frame peak. I'm coming in from the outside, sledding down the green wave about to pop up when these two blokes on short boards, inside, both paddle into the same wave, one to the left of me and one to the right. No look over the shoulder from either of them. I figure I have ROW, so I don't back off and decide to go left. All three of us take off, me in the middle. My attention is on lefthand man. I see he's cut me off, so I break right and collect the other guy. I cracked him in the shins and one of their boards got me in the head. When we all come up, they're both giving me what-for, asking me where the f--- I thought I was going. Then they start giving me a lecture how "learners" should surf elsewhere. I offer an apology and shrug the rest of it off, but I don't reckon I was actually in the wrong, unless, of course, the rule is that fault always lies with the less experienced surfer.
Any opinions? Was I in the right, or am I just a kook?
