^^^^^ Candidly, there didn't need to be a split to provide for this.
Was the only way, sadly. IWA is not ready to accept more than one section in each country as was doing at the begining. Several sections can't understand that 10 people can't be a section, can be a start but not a section with the same power than thousand ( this rule of one section one vote was logical when we sections were real unions of 100 thousands members, there are sections that in Spain they could not be not even a local union). The discussions and meetings we are having the last 3 years could not be imagined within IWA. I hope the things change in the future, but now a days I think that the fact that between 80/90% of the IWA militants decided to create something new can't be seen as a simple banality of their members. Have in mind that left IWA the militants with the biggest experience in working class organising.
It all matters. Though this discussion has been hashed out elsewhere
I'm not a fan of your premise or of much of anything else going on with the intra and inter organizational stuff.
