Martial arts is all about reaction forces. If I want to kick somebody and knock them back, I need a damn good reaction force. The most popular one is the combination of friction and gravity that you would use to stop me from pushing you backwards. Martial Artists spend years learning to make the most of available reaction forces.
I have personally knocked people backwards, sometimes off their feet, with kicks. Never once did I suffer the fate you've suggested; my stance and balance were right, and I was able to find enough reaction force to knock my target back without being knocked back myself.
Momentum is another one. If I build up some solid body momentum (by jumping), or even just momentum with the arm or leg I'm striking with (by extending it rapidly), then the equal-and-opposite-force to the one that knocks my target backwards serves to STOP my existing momentum, not knock me back equally.
Try writing about something you understand, instead of just collecting common gripes and parroting them back (to an admittedly under-educated public).
