If you do not want some of the Adsense ads to appear on the site!

[Demow]

Hello... Among the Google ads I see on the websites I visit, there are some that I do not want to see at all because they are irrelevant. For example, ads promoting Christianity targeting our youth! Can we specify the ads we want to be displayed on our website when we join the Google AdSense system? Or does Google use our site as their own property and display whichever ads or propaganda they want? Thank you...
