I do not understand the comments of people who do not like bad English. Say thank you for at least such English. Those who are not native to English use Google Translate and do not complain.
Think about this for a little while: If a native English speaking person struggles to understand something what chance is there for a non-native English speaking person to understand the same thing? Google Translate can only do basic translations based on the text it is trying to translate. What would anyone learn in school if teachers didn't correct you when you made mistakes?
Personally, whenever I do point out spelling mistakes and bad grammar it is only ever intended to help others improve their own understanding of the English language. English is not an easy language to learn and truly understand, nobody can improve if noboby tries to help others to improve. Bad English is still bad English and as such anyone reading bad English isn't really going to learn much of anything now are they?
I agree that just complaining about bad English doesn't help anyone, but pointing out the mistakes
and then including the correct spelling and/or grammar does much more to help others understand. However, pointing out such mistakes but then making mistakes in the corrections isn't actually helping anyone either!
One final thought: If English is not your native language would you correct someone who was making a mess of
your native language?
