I take Him at His word. I believe nobody can come to the Father except through Christ.
I also believe that anyone, whether Mormon, Buddhist or Jewish, who believes differently and politely offers to explain why is not adequate reason to become offended, nor does their doing so constitute a hate crime.
There are many, many Christians who would disagree with you. As I stated earlier, IMO it's comparable to someone saying, "Sherman, that child of yours is the ugliest thing I have ever seen."
It's obvious your mileage may vary.
This has been one of the strangest defenses of mormonism that I have seen on FR. One would wonder just what you WOULD find offensive.
