Stop claiming that all or even the majority of shias believe in tahreef when its not true. I mean two can play at that game.... all sunnis practice misyar.
The issue is the majority doesn't declare the 12ers who believe the Quran to be incomplete to be kaffirs.
Even though your point doesn't really make a difference, can you at least show me sources in english?
Here you go.

So let me get this straight, you post a million times how shias believe in tahreef but say that's not the main point? You are spreading false propaganda, half the threads on this forum people are claiming that shias believe in tahreef because of your lies.
The problem here is that you want to label everyone outside of Islam who doesn't agree with you. Do you know how big of a sin it is to claim other muslims to be kaffirs? Even ibn taymiyyah (who was hypocritical about this issue) said takfirism is one of the biggest sins of all time.
And about your source, I am not a hadith expert. There are two explanations I have found on the matter.
If the hadith is correct, then it is talking about the commentary that was also revealed to the prophet (pbuh). Again, tahreef of the verses of Qur'an is a complete lie. The vast vast vast vast majority of shia scholars do not believe in tahreef.
Another explanation I have researched says that the hadith is not correct, and here is the reasoning.
Kulaini was never alive to meet Ali ibn Al-Hakam
He died in 329H and he was born in the second half of the third century. There was nearly 50 years between his birth and death of imam ridha (as)
Hakam was a comapnion of Ridha (as) who died in 203H
It would be impossible for Kulaini to narrate from Al-Righa without a wasita and sometimes two more than one wasita like this hadith from al kafi.
Regardless if the hadith is true or not, Shias do not believe in Tahreef... stop being A sunni version of Fox news and spreading lies.
Your arguments are weak.
