From reading this thread, I think what the OP needs to understand most of all is that his game was not running perfectly without Bash. Perhaps he thought it was, but as was stated he was probably missing out on much of the content from FCOM as the constituent mods were overriding one another (I'm not an FCOM user but I do use MMM) and All Natural wasn't working as intended. So if he can understand that his game was
playable but not actually working as intended, I think he might appreciate the "aggressiveness" as simply mod authors and users who have been dealing with this stuff for a long time and know what is correct and what isn't. They want his game to work as it should as much as he does, but that's not going to happen until he understands that it's not functioning properly without Bash. And the likely reason it's crashing now is because he's trying to load a game that was saved on a screwy configuration with his now-proper configuration, and as was mentioned one would expect CTDs in that case.
Besides, even ignoring that awesome mods like AN require it, Bash is an incredibly useful utility for managing mods and tweaking things. Not to mention how wonderful it is to be able to merge changes to leveled lists from different mods.
Every time someone says Bash is too complicated for them, I just want to teleport them to my chair here and show them how easy it is to set up and use. It might be new to you, but once you get it installed and play with it for a few minutes, it's not complicated at all.
I'd hate to see the guy give up on this because he thought the suggestions were too aggressive; I wish there was some way to make Bash seem less intimidating because it seems so many people think it's this complicated monster that it really isn't

P.S. Thanks @ bradleyh for pointing out how to move mods around in the load order in Bash, I never figured that out because I still use OBMM to manage my load order and other various things.
