For instance in real life, you get hit, you get hit. Grabbed, tackled, eat something bad, there's no "chance to stop it" or "chance to stop getting sick", it happened.

Except that also in those circumstances people have reflex reactions. If someone grabs someone else's hand, that person's first instinctual reaction might be to jerk their hand away. That kind of thing triggers in the same amount of time. Sure, unless someone has super reflexes or martial arts training of some sort they may not be able to stop your hand grabbing theirs. But by the same token you wouldn't be able to stop them jerking their hand away. 

I'm pretty sure the unspoken rule is to always ATTEMPT, never just DO, unless you have GM permission. Instead of having Sigurd yank them around like children, say instead "Sigurd reached out with an iron grip to try and pry the bickering man and Deku apart," and then have your dialogue.

As it is, you kind of just ragdolled them around a bit, said your piece, and then walked off without giving them ANY kind of chance to respond to anything you did or said. That doesn't leave them with a lot of options besides just accepting their powerlessness in the face of your badassness. You don't wanna take freedom of options from other players because that lessens the power they have over their own character, which isn't fun.
