Just for the record, Legions attitude towards surfing is his own. It is not representative of many if any shortboarders that I know, even here on the crowd infested Gold Coast.
I have ridden shortboards since 11y.o, still do. (No neck or back problems

) I ride SUP as well. In the 3 or 4 years I have ridden SUP I have had one single drama with another surfer. He was a self proclaimed legend surfboard shaper and the real motivation for his aggro was that I refused to recognise his legend status in business dealings at an earlier time. So that's pretty much none. Saying that I approach a line up the same as I would on my shortboard and follow the same rules on either as learnt by way of back hander as a grommet.
But, I try to approach life as a considerate person, I fail from time to time and have changed my mind about people that may have left them thinking otherwise of me but I try my best and to treat my surfing the same way I live my life. I think we all mostly do the same.
These topics are quite silly really aren't they.
