In San Francisco, an interesting battle over ideology is playing out... on the side of buses.
An extremist group called the American Freedom Defense Initiative paid to place ads calling for an end to aid to all islamic countries, claiming that hatred of Jews is in the Koran.
Despite protests, the San Francisco Municipal Transportation Agency won't remove the ads - they say they're protecting free speech.
So a creative activist decided to spring into action, with a little help from superhero Kamala Khan, or Ms. Marvel.
Edina Lekovic, Director of Policy & Programs for the Muslim Public Affairs Council, joins Alex Cohen for a talk.
