Red Card Homophobia is a new organization aimed to bring attention to the fight against homophobia in soccer. The group doesn't focus on a particular country or league, but rather is focusing on the worldwide soccer culture as a whole. They have a regularly updated blog and have created a number of fliers in 15 different languages to bring attention to the issue and the new organization.
It's a group of football supporters, and their aim is to have an effect through social media. They're off to a good start. Check them out!
