First , I am not English-speaking , I learnt English besides to 2 other languages.
Second , you are so stupid to mention this , we all know that you can not judge a person on his English unless he speak something wrongly, so next time when you try to argue with someone , try not to mention this point as it shows how immature you are and how stupid you are to use this point against people, The way you speak reflects your personality, and you clearly do not understand the meaning of the argument, learn to speak realistically and logically and then argue
