For the people complaining Pierre is too much of an attack dog, wake up.
So is Larry Brock, Michelle RG, Michael Barrett, Michael Cooper, Andrew Scheer, Melissa Lantsman. Just to name a few. Yes Pierre is the lead attack dog but he leads a pack of attack dogs. Or we could use another term, like opposition, ohh wait, thats what they are.
Basically, many of us view Liberals complaining about Pierre "being an attack dog/too negative/not cooperative.." are literally complaining about Pierre and his cohorts doing their JOB as opposition. Your just upset they embarrass the Liberals.
