Facebooks ads demonstrating racial, gender and ethnical discrimination has been controversy wildly. they have got accused for allowing discriminatory ads on their platform, which they have made a policy that advertisers are to exclude discriminatory contents while making ads. the impact given by media is big, one wrong visual with wrong concept can certainly have the viewers inspired or persuaded so the contents of the ads should be justified. (like if the ads show wrong information it could have the viewers understanding as it is so the contents of ads should be appropriate)
