How can type O blood be given to other blood types if it has antibodies for both A and B positive blood?

Question

Although type O blood has antibodies for both A and B positive blood, it does not have the A or B antigens on the membranes of its blood cells. That means there are no antigens for antibodies to attach to, allowing type O blood to be the universal donor.

I got that much. I mean why don't the recipient bloods react if the anti-A and anti-B antibodies are present in the plasma (given to type A or type B)
