Animals slaughtered by Polytheists

Question :  If a person deems as lawful animals slaughtered by a Mushrik, and uses as an argument the Words of Allah:

كُلُوا مِمَّا ذُكِرَ اسْمُ اللَّهِ عَلَيْهِ إِن كُنتُم بِآيَاتِهِ مُؤْمِنِينَ

So eat of that [meat] upon which the name of Allah has been mentioned, if you are believers in His verses.

He claims that this Verse is self-explanatory, and does not accept any other argument. Is such a person to be considered as a disbeliever?

Answer : 

He who deems lawful consuming meat of animals  slaughtered by a Mushrik is wrong, not a disbeliever because he is confused. The above-mentioned Verse does not 

support his claim, because it is unanimously agreed that the meat of animals slaughtered by a Mushrik is prohibited to consume. He who has the knowledge should clarify this to him.
