You’re being pedantic in the cases you want while complaining to others when they are differently pedantic. I’m not stooping to pretending to misunderstand due to pedantry.
If you are using the term theft colloquially, which most of us are as this is not a court, legal journal, economic journal, etc. Given that colloquial means the way people generally speak, as we are now, theft has a meaning: taking something that’s not yours through force or trickery. That would mean fraud is a type of theft in this case and not a different thing altogether.
So be a pedant I guess but it’s boring and lazy-brained.
