#1...Have you EVER asked Lds missionaries & their leaders this same Question?...and if not, why the religious hypocrisy you're exhibiting?
If this is a "fair question," then it's also a question as to why LDS are constantly proselytizing Christians the world over.
#2...You seem to assume that ALL religious beliefs result in "freedom"
The apostle Paul didn't operate under a mistaken assumption:
To the Galatians: 4 This matter arose because some false believers had infiltrated our ranks to spy on the freedom we have in Christ Jesus and to make us slaves. 5 We did not give in to them for a moment, so that the truth of the gospel might be preserved for you.
You see when legalism is spread, what happens is EXACTLY how Jesus described in Matthew 23: 15 “Woe to you, teachers of the law and Pharisees, you hypocrites! You travel over land and sea to win a single convert, and when you have succeeded, you make them twice as much a child of hell as you are."
Legalism is NEVER content to "leave others alone" -- just like the masses of Mormon missionaries traverse land & sea like the Pharisees did!
Legalism leaves many in bondage; that is hardly "freedom"...
No one has to invite them in to proselytize.
