What do you guys think about christians using your scriptures and calling it their Old Testament/holy bible?

Just want to get some thoughts.

I’m a non christian and non Jew. I was in the store the other day and saw the religion section, with tons of bibles. Bibles include New Testament, and Old Testament, (which is you guys scripture).

So I was wondering if you guys find that ok, or if you find it disrespectful that your scriptures are sold as part of the christian scriptures

And I was wondering why The Hebrew Tanakh is not sold on it’s own in stores. Do you guys think The Tanakh should be sold as a seperate book in bookstores in Canada? I think it should but I want to get your thoughts Thank you
