So what you're saying is you don't want companies, artists or anyone else to have an opinion, especially if it disagrees with yours. This is an election year. Lots of people on both sides of the issue consider it extremely important. The fact that some people such as Chris Martin express his opinion is hardly surprising. You don't have to like what they say, but you can't deny they have a right to say it.
BTW, Carly Firorina is an advisor to McCain. She's a widely known figure in the computer industry. Do you have a problem with her expressing her opinion, or is just people who support Obama and Prop 8 in CA?
