Why are the Filipino people so unfair with us Chinoys?

I almost killed a chinoy yesterday, he yelled at me when i was buying something from his hardware, at first i controlled myself because he looked like he has a bad day from his employee and he turned his anger on me, he keeps yelling at me whenever i politely asked for the stuff i need, until i got pissed off, i told him to stop yelling at me or else mamalasin ka! He stared furiosly and again shouted on my face, so what i did is i pulled my caliber .45 and pointed on his fcking face and ****** the hammer, he turned pale and his jaw was down to his shock! I told him sumigaw ka pa pasasabugin ko yang utak mo ptang ina ka! He was shock and nangatal ang ptang inang intsik! Now i hate tsinoy bcoz of that encounter! you have a bad values against pinoy! You think we are the lowest mammal, remember this is not your territory so bare with us!
