Correcting the first review:
"According to this people, Mormons don't know a thing about Christ because they present a pageant about Him"
If you actually watched the presentations you'd know this is false. They rather don't know about Christ because Mormonism is a false cult.
"so they are eager to make endless manifestations against the pageant itself."
Try "presentations" instead of "manifestation" which rather means
"outward or perceptible indication"
"I don't get why Evangelic people are so blind to Mormons' beliefs and practices and just let them be!" Again you either didn't view the presentations or are deliberately misrepresenting them since far from being blind to Mormon falsehoods and deceit, they rather expose thm. While in one say Islam is more overtly dangerous a cult, Mormonism is far more subtle and thus slips under the radar to destroy the unsuspecting.

According to this people, Mormons don't know a thing about Christ because they present a pageant about Him, so they are eager to make endless manifestations against the pageant itself. I don't get why Evangelic people are so blind to Mormons' beliefs and practices and just let them be!
