Why do they keep pushing the narrative that we worship the same god?

This LTE was originally sent in in to the St. Cloud Times in February 2019. It was resubmitted earlier this summer.  It is 299 words and follows all their requirements:

I have had some less than pleasant run-ins with people who are active in the interfaith dialog movement. My questions about how they can promote to both Christians (no matter what sect) and to Muslims (again, no matter the sect) that we worship the same god when this is 100% NOT true has not been met with a kind answer, ever. This is a reasonable question, as for someone to state to me that "God is not the Trinity and Jesus did not die on the cross" is blasphemy (1 Corinthians 3:11) and the same is true to tell a Muslim that their Allah is the same as God. (Qur'an 112:3 part 2 and Qur'an 4:156-157 ).

In order for there to be a solid foundation in any relationship, we must start with trust and the truth. The truth is Christianity is the knowledge that God is 3 in one: Father, Son, and Holy Spirit; that Jesus, the son of God, died on the cross to save man from burning in hell for his sin. Another truth is Islam follows the teachings of Allah; Allah who was not begotten nor did he begot, and their Isa (Jesus) was neither killed nor crucified (Qur'an 6:157).

I am hoping to get a clear answer as to why the interfaith movement believes it is not OK for us to worship a different god? And if it is OK, then why is the interfaith movement in Minnesota lying to portray similarities that do not exist? I thought we were promoting diversity. We have so many people who are becoming atheist or agnostic because it takes lots of time and research to cut through all the confusion being created; yet none of this needs to be so complicated, especially when we start with truth.
