Can anyone figure out why people mix up 'Hindu' (religion) with 'Hindi' (language)?

Is it a lack of awareness/ ignorance or typo?

I have seen a lot of people confusing Hindu with Hindi - both are different (a Hindu may or may not speak Hindi - they can speak Tamil, Marathi, Punjabi, Gujarati, Bengali etc)

it is like Islam/muslim. they call it the Muslim religion, but it has to be Islam.

Hindu/hindi sound alike. other than to Pol who speak SanskritICCanguages Hindu and Hindi is like potato and potaato..

u and i

Good old fashioned American ignorance

Hehehehe! So I see that my ignorance prompted you to post a question. My first language is Spanish and in it, a person from India is called Indy. So what I did was a phonetically translation. So as to answer your question, at least in my case I'd say it's ignorance.

Thanks for the correction, my friend.

well they words sounds the same except for the u and the i. just correct them.
