I have no idea why do the women hate soft techniques
Victor, if I may speak for women, they don't hate soft techniques. They hate being treated differently on the mat. They hate the implied belief that they are too delicate to take the same treatment as any other uke. If you threw every technique soft for every uke, no one would have a problem.
I, myself, do not like soft techniques 100% of the time... if I'm in that situation I'll normally go to one of my sempai and asked to be thrown around until I'm out of breath. So I do not blame women for taking a stand on this one.
