How can I stop sounding like a big talker?

I am not English nor American but I am a graduate of English language and literature. so, I read a lot of books during my college years and I have good communication skills but I can't help sounding like a big and rhetorical talker. Even on quora I ask a lot of questions and people go through my profile and say that why are you asking rhetorical questions and answers. However, I don't like drawing attention. How can I stop sounding like a rhetorical speaker who is obviously literature graduate?
