"Personally, I hold the opposite opinion." Is this sentence grammatically correct?
Here's an extract from my essay: "....Recently, some people argue that it is unfair that professional workers such as doctors, lawyers and teachers don’t enjoy the same income as those sports and entertainment personalities, since they make a greater contribution to society. Personally, I hold the opposite opinion."
Some say that the last sentence is incorrect—If “I” is not “personally”, then “who” should be ? In short, personally is an encumbrance. Is it better to say"Personally (speaking), ...(the opinion/ phenomenon)" or is it OK with this sentence?
P.S. Do you think that the first sentence is "unclear, problematic, run-on, too long, has too many antecedents" ?
Thanks for your kind suggestion!
