Make no bones about ...

to make no bones about sth. nicht zögern, keinen Hehl aus etwas machen, mit seiner Meinung nicht hinter dem Berg halten

to make no bones about sth.
To say clearly what you think or feel about something, however unpleasant or awkward it may be.
To make no bones about something means to say something in a way that leaves no doubt, or to have no objection to it.

The expression comes from fifteenth century England...if someone wanted to show that they were dissatisfied with something, they would find bones in it - a reference to finding bones in soup, which was not a pleasant discovery!
Therefore, finding bones was bad, and no bones was good. If you found no bones, you were able to enjoy the meal with no objections! (Quelle: Learn English)
