I don't believe this has anything to do with fans in the stands, but TV advertisers complaining they won't market on MLS matches with their microphones picking up our swear words. Again, they want to use us to sell, so we have to say what they want us to say.
Yes, swearing is offensive to people and I don't disagree. But I don't like being an MLS tool, and used as they command me to. That I take huge issue with. If they don't want swear words on TV, put your bloody "fan" microphones at centre half where in many stadiums, it's empty.
