english is just the same as any languages

people always debate about the differences of languages in this world.
most of us think bahasa melayu is much more important because it's our mother tongue language.
but some of us think that english is much more proper for us to use in our daily conversation. however... does fuck, assholes, damn and morons are properly used words in this matter?
is it important to say all those words? it's just the same as bahasa melayu.
is it proper for us to speak in malay if we oftenly use bodo, babi, pukimak, buto kepala hang and as such?
it's not about the languages that i want to talk about.
it's about how the people use it in a right way. or the other way around.
i admit that i'm one of the people who always misuse my language.
but nevertheless, the importance of how we apply those words in our lives and how we deliver it that matters//
for me, i'm a very harsh young woman. I've slept on the streets for more than 3 months.
belum lagi jumpa suami saya.
dia dah empat tahun hidup tanpa rumah.
we've met a lot of people and these kind of people who always use harsh words are actually quite nice people.
they may don't have the proper way to deliver their words. but they know what they want to say rather than some of us use english and international languages. think they are great and wise. but they don't know a single thing about what they're saying.
i'm sorry for my grammar errors and such.
I'm still learning. good day =)
