Of course if you're physically trying to block someone you're already using violence. You're threatening to restrict their movements with your body and thus if you receive the same you can hardly call foul.*
I don't think this would have even made the news except for the fact that the 'elbowed' MP was a woman. There's quite a double-standard here.
She wants to be in with the boys, and be respected and yet when it comes to this sort of thing, she wants special treatment. She jumped in there and used her body to block others but then got upset that in the subsequent melee she got elbowed in the chest.
If you can't take the heat, get out of the kitchen.
If she wants to be treated as an equal then she can't pull the woman card and expect male MP's to exercise chivalry. If chivalry is the order of the day, then she shouldn't be there to begin with.
If she was a man and got elbowed no one would have cared and in fact a man making noise about it would have been laughed at as a wimp.
When women want to act like men, they shouldn't be surprised to be treated as the same. The whole episode was absurd but I think the silliest part (in the end) was Trudeau having to publically eat crow and apologise over and over again.
*It's a separate issue but a lot of so-called pacifists have also missed this point. They are pacifists to a point but in another sense they're using violence, albeit in a different manner. It's rooted in shaming but is still a form of political aggression. Christian Pacifism if we want to call it that, is or ought to be somewhat different.
