The International Rugby Board (IRB) cannot turn around and accuse us of halting the development of their game in new territories without making themselves look hypocritical. It would generate a lot of media coverage and allow the Rugby League International Federation (RLIF) -- and their affiliates -- to talk about RU's curtailment of RL since 1895. Lots of publications and television networks would be interested in speaking with the RLIF and and its affiliates because it would spike the newsworthiness of the story.
The beauty of doing this is it would catch-on with people as it would be viewed as a fashionable trend. I reckon a fair amount of the youth would support RL over RU because they would see it as being "cool" to rebel against the bigger, more established sport of RU.
Demonising the sport of RU for its thuggish tactics could open up a niche for Rugby League development within non-Caucasoid communities in South Africa, New Zealand and possibly the USA.
South Africa
It wouldn't surprise me to see a lot of blacks in South Africa take up Rugby League because Rugby Union is a white man's sport in RSA; the vast majority of the South African Rugby Union's registered players are Caucasian.
New Zealand
The same angle could be pushed among the Maoris who believe they're a marginalised class. Bringing attention to the fact a lot of Polynesians play in the NRL and ESL would make them feel welcome as they would see Rugby League is for everyone.
USA
America's black population have not taken to Rugby Union. The RLIF and the AMNRL could bring them onside by a) showing them the high amount of Polynesians who play the game and b) how they can relate to the game as it has been victimised like they have been.
The aforementioned tactics may not be underhanded. However, if they have the potential to strengthen Rugby League at Rugby Union's expense then I think they should be implemented by the RLIF, SARL, NZRL, AMNRL and the PNGRFL.
ps. I do not want the RLIF to spread evil liberalised/PC propaganda to stir up hatred between blacks and whites. Instead, I wnat the RLIF to promote the fact that RL is a sport for everyone.
