We each bring our conceptions on that topic to D&D. Yours are fine, for your table. Others may have very different starting points. Ed Greenwood, for example, wrote some stories in which gods change, and a mortal may well remember the days back before Kelemvor seized the portfolio of death from Cyric in the Year of the Banner (1368 DR).
Which is true, and I fully support. I also fully accept and understand that I may not be the DM for everyone. I don't allow evil characters, I view orcs as monsters not as human's with bad dental work, Gruumsh is evil, etc.
If it wasn't clear, what I was objecting to was the holier than thou attitude and that how I run my games is somehow wrong because I view Gruumsh as an evil god who who should not provide power to someone who is not fully supporting the way of the orc. Apparently all DMs everywhere should let the players dictate what the gods are and how they'll react to someone not fully supporting their chosen people.
you are putting your own needs above your players and quite frankly that's a great way to LOSE those players when they realize you are unbending and unable to compromise and thus probably won't be a fun DM to play with because of some lame "My way or the highway" attitude.
So obviously I'm just not a fun DM to play with because I have decided on a cosmology where evil gods are, well, evil. I'll have to tell my players that sometime, that they've mistakenly let me DM for years. They'll be quite disappointed.
