Why do people hate English

English is an international language, it is spoken in almost every country in the world which makes it a very popular language.
Some people may dislike this language. They think of it as a type of evangelism, so they stop learning it and even speaking it.
I remember here something it may even be a rumor that one of our English teaching professors was about to be expelled or transferred to another university just because five percent of the students understand what he says. Hence, the rest of the students do not understand what he says.

It's very frustrating not to learn a language, and in my opinion I think that we should learn a language in order to be safe from them and to know exactly what they say against us.
I know it's hard to learn a language but it's not a mission impossible, so if anyone wants to learn something, he must work hard to get it learnt
