"As a French" ne veut rien dire en anglais. Il faut rajouter man, person ou quelquechose. Frenchman, French person, French citizen.
Pedantry attracts dislike. One may be right to state something, yet wrong to call it out in public.
"Quelquechose" doesn't mean anything in French. It's written "quelque chose".
Nor "Frenchie" while we're on the topic. It sounds really weird. It's also commonly used to refer to a french bulldog !
The demonym for France is "French," so it's not wrong (even if it doesn't sound right.)
