Why do other people assume other religions are wrong?

Jesus answered, “I am the way and the truth and the life. No one comes to the Father except through me. John 14:6

The color white has no hint of any other color in it. A pure white is absent of any discoloration. Add a hint of black and white becomes off-white. Add some more and it becomes gray. Add every color at the same time and you get black.

If you want to know if the color swatch in your hand is white, you have to hold it up to the purest form of white, a standard, then you can tell.

But where is the pure white, untainted by the world, standard? The truth is clearly found in the life, words and authority of Jesus Christ. Any religion that follows Christ according to His revealed Word, the Bible, would be considered “true.”

Judgment against other religions is based on truth, not experience, feeling, tradition or the presence of “good people.” Just because someone feels their faith is true, does not make it true. The standard of truth is Jesus Christ.  Just because a faith has a hint of truth doesn't make it true.  You wouldn't call yellow white because it has some white in it.

We should never assume someone’s faith is wrong because of what we think is true, but hold them up to the standard set before us by Jesus Christ as true.  That's not an assumption.  That's a fact.
