violent motherfuckers crowdkilling are pissing me off

so, lately i´ve been going to deathcore/metalcore/beatdown shows in my local scene and i´m kinda of sick of muscular tall dudes beating the shit up people half their size and making people have a shitty time on amazing bands.
And i HATE when they hit people who aren´t even on the pit and drag them in (like it happend to me last time, i was at the back and some guy grabbed me from the back and threw me into the middle of the pit and i got badly kicked all over).
And on a show i went a few days ago, a friend of mine got into a fight with a fucking fattass for punching him many times in the head.
i´m not against moshing or crowdkilling as LONG it´s with some care for your surroundings and only in the pit. 
But rn i hate seeing violent people ruining everyone´s fun and turning the mosh pit exclusively for giants with muscles.
