Why do some people think that putting a ? at the end of a statement automatically makes it a question?

These people obviously lack the intelligence to form a declarative sentence. Either that or they lack the self esteem to make a declarative sentence. Some people always want others to be in agreement to serve as a support for their own psyche.

There are people in this multicultural, multi-ethnic, multi-language world, who have only begun learning English. They wouldn't sometimes know how to ask a proper question. So they just use the question mark to demonstrate what they're saying is actually a question.

yes i see your point i dont think it matters because most of the time i dont use a question mark and people still understand that im asking a question

like if i write 'why dont use change the password'

people know im asking a question because i said'why'

hope you get a good answer!

No, because sometimes, its a rhetorical question....one that does not require an answer.

I think the ? appears automatically, I wrote a question and the ? appeared on its own

why not you just did right?

ohhhh ok..
