To which extent these claims are true, and how true is that you won't tell these while doing missionary work?
That God is glorified [elevated] human, who has body of flesh and blood
Basically, yes. We don't go into this specifically (we don't teach doctrine that deep/obscure as missionaries) but a lot of people are aware of this and we answer honestly any questions that are asked.
That Jesus is Satan's brother,
We believe this (we believe that they are brothers in the same sense that we are all brothers and sisters of both of them) but again, don't see the need to bring it up. if people ask, we tell them.
his death on cross absolves only the original sin,
We don't believe in Original Sin.
and that Jesus' father is human consisting of flesh and bones
Jesus' father is God, so see above.
That there's actually uncountable number of gods
Sure (for a wide enough definition of "god"), although we really only worship/focus on God the Father.
and that good men can be elevated as gods in the mormon church,
Yes - as well as women.
Polygamy is not necessary for salvation.
because the new union that gives salvation is polygamy, not the protection of the blood of Christ
Nope, salvation is through the Atonement of Christ.
That there won't be salvation outside the mormon church
Well, yes and no - salvation is conditional on receiving ordinances that currently only the LDS Church has the authority to perform, but that doesn't mean non-Mormons can't get into heaven.
That they join long time ago dead women to now living Mormon priests with sealing [?],
Not true.
because acoording to their doctrine no woman can be saved without a mormon husband
Well, again - to attain the
highest level of salvation a woman needs to be sealed to a man - and a man to a woman.
Their sacred underwear, "Garment", that every mormon who goes through temple [-education] promises to use 24h a day.
True, sure - we discuss this as missionaries with anyone who asks but normally discuss it more if/when they are preparing to go to the temple. It is not worn in situations where underwear isn't normally worn, is all I will say.
where the tenth, 10% of your gross income, or other donations are used. In mormon theology the tenth is a law, irrevocable, stated by God. If you don't pay the tenth, you're stealing from the God.
Yes, to be a member in good standing requires paying a tithe of 10% of one's income - as missionaries we tell people this beforehand, no point in surprising them.
Of course, what we tell people
at their door is much less in depth than what we tell them if they agree for us to teach them the missionary lessons . . .
I hope that helps.
One other thing - the name of the organization that made this list seems atheist-oriented, yet many of these claims are objections on theological lines; eg why should someone "supporting the victims of religion" care whether someone believes in one god, three, or 437, and why should it matter whether salvation which won't actually occur comes through polygamy, the blood of Christ, or one's one actions? Just curious - I have heard other Christians and atheists both criticizing us, but their objections shouldn't really overlap that much.
