Diction and accents are a matter of locality or would say lugha ya mama. You might think that Ugandan accent is funny wait untill you speak to he who english is the mother tongue and he would laugh at your funny accent. Thinking of which even in UK they have differents accents depending again on locality.
Albert,
Ugandan accent is not a disability to be excused by education standards. It is a matter of who you are. Nigerian are proud of their pidgin english so are the jamaicans.
Just my two cents
