"Expand All Conversations" GUI Script-Mail

Question

Hi,
I prefer to use the "Expand All Conversations" view in Mail, however, it doesn't automatically enable after you recieve new messages, so I wrote a GUI script 2 days that selects the "Expand All Conversations" menu (under View) in Mail and I then setup a rule (To Every Message-Run this script).
My only problem is that now whenever I get a new email, the active program switches to Mail (which is extremely annoying, especially as I have assigned Mail to another Desktop!)
Here is the script:
tell application "Mail" to activate
tell application "System Events" to tell process "Mail"
          tell menu bar 1
                    tell menu bar item "View"
                              tell menu "View"
                                        click menu item "Expand All Conversations"
                                        tell menu "Expand All Conversations"
                                        end tell
                              end tell
                    end tell
          end tell
end tell
Does anyone know a way to work around the "Activate Mail" line of this script, or another way of doing the same thing without using a script?
Thanks.

Actually, just avoid the first line:
tell application "System Events" to tell process "Mail"
     tell menu bar 1
          tell menu bar item "View"
               tell menu "View"
                    click menu item "Expand All Conversations"
                    tell menu "Expand All Conversations"
                    end tell
               end tell
          end tell
     end tell
end tell
This can run in the background.
