BBC refuses free airtime to Gaza appeal

How does one interpret this decision? For this to happen, somebody powerful decided to take sides. If you do, there has to be a reason for it. A form of self-censorship, perhaps, that tries to make people believe that the Isreali.Palestinian situation is like the Catholic/Orange dispute and maintain 'balance? But in this instance, objectively, there is a humanitarian crisis. To deny airtime is to prevent the public from participating in making life better for people in Gaza. Why would anyone make that kind of decision??. . .
