Purple, X, both of you cut this out. I know I'm not a GM here, but this spans all the RPGs, and I'm tired of it.
Purple Man, I wasn't blaming you for starting things, but the comment I commented on just inflames things further. You feel you're right, so be the bigger man and just move on if that comes up. Don't instigate arguments where there shouldn't be any.
Red X, it seems like you are the only one who gets upset when PM suggests some ideas. If somebody doesn't want to use the ideas, than they won't. You've shown a lot of maturity in the past, so why can't you just ignore PM's ideas, or, better yet, add some constructive criticism to them, what's the worst that can happen there? The player doesn't use the idea? Big deal, you still exercised your creativity and that cannont be a bad thing.
