I dont know why you are against that verse, because there are Christians who understand that verse and are actually agreeing with it. The reason some Christians agree with that verse is because they know who the subject is in that verse, and I hope that I telling you the subject of that verse will change your mind.
The subject of verse 5:116 are the Maryan Christian Cult. The Maryan Cult were people in the Fifth century A.D. who spread the belief that Jesus(pbuh) and his mother Mary(as) would be two seperate gods beside God. And therefore God spoke out only against them. The minority of the Maryans believed that mary was the mother of god, through whom he produced a physical son. According to Christianity this was and is blasphemy, and therefore agree with the verse 5:116.
And behold! God will say: "O Jesus, the son of Mary, didst thou say unto men, 'Worship me and my mother as gods in derogation of God,?' He will say: 'Glory to Thee! Never could I say what I had no right (to say). Had I said such a thing, Thou wouldst indeed have known it. Thou knowest what is in my heart, though I know not what is in Thine. For Thou knowest in full all that is hidden.'" (Surah 5 Maida, verse 116)
