why is judaism better about keeping out the losers?

[MatthewColorado]

Going back to the first post, I think psalm 1 gives us a good perspective. To loosely quote or paraphrase; blessed are those who don't walk in the council of the wicked.
Bringing wicked people among you is more likely going to cause the wickedness of the perdón to rub off on the righteous than the other way around. There are better ways to I spire the wicked person and ultimately, it is the wicked person's place to choose life and torah, not to have everyone trying to covert him /her. I think that it's not bad at all to try and inspire good in them but I dont think this should come at the expense of the wellbeing of the righteous.

I don't know if bringing addicts, kleptomanics, narcissistic abusers and serial adulterers (etc etc) into Christian churches has ever reformed them, but I certainly wouldn't be willing to subject fellow Jews to people that could bring harm to them overtly or covertly, however, if the person did serious teshuvah, and became zealous for G-d, then they would be more than welcome, if it  were up to me, so I get it.

I have to wonder if ,from a Kabbalistic view, Christianity accepting in people that are emotionally distressed, but them getting exposure to any amount of Torah is like a spiritual preparation either later in that life or in another incarnation. Like you say for me personally if people do tshuvah and follow the mitzvot that is reason to support them. I do not know why anyone that can clearly articulate their love and observance of Torah should be treated like a leper as i was, but that is their problem and not mine i treat everyone as an individual and do not make assumptions until they speak and act for themselves. 

Hopefully once find a good community it is an emotionally mentally and spiritually healthy group that is supportive and really in tune with creation. So far 2/3 classes i have taken the Two Reform Rabbi's i had spent the first 10 minutes talking bad about Orthodoxy as a whole and giving the students a sense that the Orthodox are unintelligent cavemen stuck in the past that are usually wrong anyways. She spent her hour teaching students about her opinion's not about Torah knowledge. Obviously from a neutral point of view there is no reason to state other thing other than the facts of the matter, and for supposedly learned Jew's to bash 90% of where they come from is really disturbing. On the contrast the one class with a non Reform Rabbi was full of respect and admiration for the Torah, and really solid concepts like one God, mitzvot, tikkun olam. 

Maybe it is possible that Reform as well is kind of like an entry point for someone completely unfamiliar with the culture and language. 

What are your thoughts?
