Find me one credentialled authority that is willing to claim that doing a few basic resistance training exercise sessions for 20-30 minutes two or three times per week will interefere with the performance of any kind of movement skill whatsoever, other than movements extremely similar to the resistance exercises themselves, and sign his or her name to the statement.
See, the problem is... and other people have pointed it out specifically... that you simply haven't read what was written and you've made a complex and emotional strawman argument. Let me phrase it another way using weights as an example:
Let's say you want to learn to lift weights in a new and unique method of using the body, one which changes the way force-directions are generated by the body and also a way which develops some of the fascia and myofascial layers so that they in effect become a body-global type of "weight-lifter's belt". The movement system is unique also because the middle of the body has to be trained to manipulate the force directions without letting the shoulder muscles initiate forces (that would disrupt the forces you're trying to generate). And the big criterion on top of that is that you want this to become your new, instinctive way of moving.
So you start off moving with no weights, but only with the efforts to coordinate this new form of movement. You pretty much lose your ability and power in some things while you're re-coordinating this, but it's worth it (although you can of course do it in half-measures and wind up with a lesser final product) to re-pattern your movements.
What you're suggesting (and which I'm speaking against) is that several time a week you should break your re-patterning attempts and simply go back to the old way of movement. My comment was that it was counter-productive to do that. Your "muscle memory" stuff was your own schtick and it misses the point.
