While in beta, the dividing line is still being defined so the closer you get to the ontopic/offtopic/objective/subjective line, the more chance someone will find it off topic -
From experience on other sites, keeping things objective does really help. Some folks will see anything 'not site focused' as worthy of a downvote. Others will be very rigid with the rules (I know I have on occasion - on this site and others)
There is still value in asking the question if you think it is just on the right side of the line, but if you have doubts, asking in meta should always help.
In terms of being emotional - better if you can step away from the personal involvement, sure, but hey - everyone does that sort of thing occasionally, so I wouldn't take it to heart.
