Not everything is to be construed as Mukzto.
I see far too many people say to kids that it is Muktzah to do so & so on Shabbos. Muktzoh & Melocho are not the same, and are certainly not interchangeable words nor terminology.
BTY Mukzto is as most mid’Rabonon, whereas Melocho rises all the way to a violation of the 4th commandment.
