Flybeeeee - sorry you got bashed about a bit. It does happen quite a lot here.
I'm afraid that you touched a nerve and got the pointy end of a couple of sharp sticks; don't take it to heart!
As for the incident, I'm sure the XLA captain will regret it for ages, as will the many other pilots who have nudged something while taxiing, thinking that they were clear...MYT 330 in YVR springs to mind as another recent example.
There for the grace of God go an awful lot of us...we just have to be even more careful.
