“apushetyid, Why is making decisions deserving of respect? This is a part of life.”
Yes, and if you want someone to take you seriously, you have to respect them as a human being, which means you acknowledge their right to make a decision. You dont have to respect the decisions that they made, (and you should let them know that as well – being two faced is worse than summarily dismissing someone out of hand).
“What about the Eirov Rav and Korach? In the midbar with the greatest leaders they made poor choices.”
How did Moshe Rabbeinu deal with them?
“Do we also need to “respect” Joe Stalin (or at least that he made decisions, if not the decisions made)? Or Bernie Madoff?”
Are you trying to reach out to them and help them? Stalin firmly believed in his cause as did Bernie Madoff (they shared the same cause by the way, get rich off everyone else, although their means were different). You are certainly entitled to try your approach when dealing with OTD people, I just have a hard time believing “shaigetz get back in the beis medrash, I dont care if you are angry at the whole world” is going to get anyone one iota closer to Hashem.
