You can have poor English and be not ignorant. You can speak foreign languages and be a brilliant scientist. Many doctors have poor handwriting. But are brilliant in their skill. You are quite foolish and ignorant.
If you were raised in an English-speaking country and attended English classes in every single grade 1-12, then NO!!! .... You should have some basic degree of English speaking and writing skills that the average high schoolers possess.
Your examples are not about YOU! They are hypotheticals.
Are you really saying you are brilliant in spite of your poor English skills? Did you grow up speaking a non-English language, only to start learning English in high school or college?
Stop trying to excuse your own ignorance by attacking everyone else.
You are quite foolish, ignorant and stupid.
My college German professor was a Czechoslovakian Jew. He spent the last few months of WWII hidden in a concentration camp. Were he not hidden, he would have been murdered, just like the majority of his family who were captured.
He came to the US after high school and attended college. He's now fluent in 8 languages, conversant in 12 languages, and his English is as perfect as anyone's who was born in an English-speaking country.
Put a cork in your "foreign language" pie hole.
