I thought you are an educated Muslimah, I hope your _harsh_ statement meant to condemn the false aqeedah of Ehle-Tasheeh, but it is not aligned with the Rasool Allah S.A.W Sunnah.
I mean the tone of your post is way too rude!! If you dont like Shia because they do shirk, they abuse Sahab R.A.A., then rest assure that you will not be accountable for their act in your grave or on the day of the judgement! nor calling someone Kaffir will give rise to your Emaan, just in case if you think you got right to call them Kaffir.
And if you want to hate, then hate their act (shirk, abusing Sahaba R.A.A etc), if you want to condemn, then condemn their act which is not aligned with Quran or Sunnah. And condemn the way the Rasool Allah S.A.W. used to condemned.
Someone asked a Hindu doctor in Karachi, Pakistan, that why Hindu do Shirk and do Sajda in front of a stone idol? the Hindu replied why the Muslim do sajda in front of stone-home (Baitullah)? Muslim replied we do not worship Baitullah, its just a direction, in reality the sajda is for Allah S.W.T. The hindu replied, similarly we do sajda in front of Idol, believing that we are doing sajda to our God. Nice logic, but still SHIRK is an attribute of Hinduism. The fact remain fact, words can be used intelligently, but underlying believe remain there.
What is the definition of Kaffir? The one who deny the existence of Allah S.W.T and his oneness, dont believe in Rasool Allah S.A.W as a rasool from Allah S.W.T, dont believe in Angels, on the day of judgement etc.
What is the definition of Shirk? The believe in more than one entity having supreme authority
Shia believe in Allah S.W.T., they believe in Rasool Allah S.A.W. as the last prophet, BUT they count Hazrat Ali R.A. and their Imams as supreme authority, see the SHIRK? I do not see how come they tagged as Kaffir?
Any Quranic verse or Hadith will be appreciated, where its appropriate to call some person who believe in Allah S.W.T and Rasool Allah S.A.W and have some aqeedah not of your school of thought and its okay to call him/her Kaffir? Do you call Jew or Christian Kaffir as well?
No one has authority to call someone Kaffir from within Muslims.
For Allah S.W.T sake, please stop thinking that 'I am on the sirat-al-mustaqeem because I follow XYZ school-of-thoght', in Surah Baqra, Allah S.W.T. is specially calling Jews but in general everyone who believes so, which means that Has Allah S.W.T. made any commitment and bound to it with them (Jews) that Allah S.W.T. has to let them enter Jannah, rather only those will enter in the Jannah who have abide the laws of Allah S.W.T. In following few verses Allah S.W.T include Saabi, Christians, Yahoodi etc in the list of day-dreamers.
