But we must realise that any chilul Shabos including texting is an act of REBELLION against Hashem – tantamount to denying (ch’v) that He created the world.
Not true. You’re describing every act of chillul Shabbos as one of a mumar l’hachis. I’d say that that’s not true — most cases of chillul Shabbos (including teens texting on Shabbos) is far more likely to be a case of a mumar l’tayavon, which is most definitely not a rebellion, nor a denial of His creation of the world.
