I try to respond to everything, good or bad. I get a lot of suggestions from players, and I genuinely try to implement what I can as long as it doesn't drastically add to the workload or require changes to core systems (and it fits within the overall theme/story). That being said, some people request stuff that'd require a complete overhaul or just totally change the scope of the game and those are always odd. Looking at the guys post history though I think he's just a troll or doing this for laughs.
Either way, I agree, if you aren't comfortable with something then maybe don't see it out.
