Mdd,
You do realize that there are two different status of Mumrim, one is מומר לתיאבון and one is להכעיס. One who is sort of a emotional disturbed person (many are, as suicidal rates has proven so) although I don’t think he falls within the category of שוטה (though you could argue that yes, as some uphold so, as has been written at length on the back n forth response’ regarding the גט מקליווא.) But nor is he to be termed as להכעיס
