God is a personal god. Nobody can turn anybody from Him.
No...there are some actions that people can do that facilitate the turning away from God, such as chasing him away from a place of worship...
Instead of lashing others,
No...we are not supposed to implement huduud unless the offender clearly brings it upon himself. Even if they testify to a wrong they are asked to repeat four times and repeat the crime they have committed and a person is easily absolved of their sins if they show a figure of repentance...Historically huduud were rarely implemented and used instead as a policy of deterrence to prevent the decay of morality in public and it has worked.
we are supposed to dismiss them until they change their ways.
If you dismiss them while they are sinning then you shun them in their greatest time of need. Religion becomes quite useless if that is the course taken.
Our sins were absolved by Jesus, and loping with troublemakers and people who speak against him is very costly.
There is no such thing as "loping with troublemakers" that would imply consenting to illicit activity or encouraging it. Instead we are told
The Prophet (sal Allahu alaihi wa sallam) said, “Whoever among you sees an evil action, then let him change it with his hand [by taking action]; if he cannot, then with his tongue [by speaking out]; and if he cannot, then with his heart – and that is the weakest of faith.”
Let him
change not shun the action, by disfellowshipping you are not helping you are abandoning those who are in need of help.
Furthermore I find the idea of Jesus (PBUH) "dying" for my sins to be inherently wrong because according to you if I die right now I will be "punished" so apparently he did not. The idea that I am inherently bad or born with a sin I did not commit is repulsive in itself and a perversion of the sense of justice. A man is judged according to his piety not the piety of his father.
