I was at last night's (Sunday 4/20) game up in the cheap 400 level seats. It seemed that the Mets fans that got heckled the most were the most vocal. I saw plenty of Mets fans that were just watching the game and cheering when their team actually did something. These people were left alone for the most part. The ones doing their little cheers every five minutes regardless of what happened in the game deserve to get boo'd and heckled. You can't come to an opposing teams stadium and expect to be able to cheer like you are at home.
