Threatening breaking of jaws thats just macho bs, but it sounds good on the internet. Oh I know its not a threat, its a promise. It's be said before there is always someone out there bigger, faster and meaner. There are people who like to fight, there are people who train to fight, there are people who don't mind taking a couple of shots if it means they can destroy you, there are people who have black hearts that would think nothing of breaking you knees or worse in a fight and have the knowledge to do so.

While I can see the egoic desire to fight a sexual rival my vote goes against violence, and especially against threats of violence.
Now back to the topic at hand, C-eyes need to set a boundary.
Don't try and be perfect about it don't put that burden on yourself as well. Do you think an "alpha" cares if they say the right thing? Just say something, don't let these things slide.
