I actually disagree with the claim that using descriptive editorials ruins role play. To be honest, I don't think the purpose of RP is absolute realism, but rather something closer to similarity of realism. Instead of seeing these descriptive editorials as providing unrealistic information to the other player you're RPing with, I think they function in two ways.
1) They provide a certain mood or context of personality/attitude of the character, allowing the other player to get a sense of what the character is thinking/feeling and therefore can choose to interact accordingly.
2) They offer a little bit of narrative play. Since RP is similar to creating stories, when we role play with someone else, we're trying to not just engage their character, but the player. Small side notes to RPs, I think, provide amusing and engaging incentives for players to engage with another character.
Therefore, statements such as: /me smells Abominogs breath, gags and wonders if he had been eating consumers again and concludes that whatever he had eaten it was best to stand a little further away, set a certain mood for the character (namely, a slightly comic mood that simply gagging and stepping away might not provide) and offers some amusing comic relief for the player, who either might choose to ignore or play along with the joke.
What is harmless about these editorials is that since they are asides, the other player can choose whether or not to acknowledge the added details and act accordingly in the RP. That player can decide to ignore the consumer breath suggestion, or play along with it
e.g. /me burps and then blushes awkwardly, mumbling something about eating some meat that didn't agree with her
or /me looks slightly offended at the stranger who stepped away from her, after having discreetly checked her breath and finding nothing wrong with it.
or if you want to ignore it... /me seems not to notice the strangers reaction
In all honesty, if you find these kind of asides frustrating, I think the best thing to do would be ignore it. Chastizing players for using them I think implies a certain amount of bad faith (i.e. assumes that the other player is using the editorials to ruin the RP rather than make genuine attempts to engage). They are easy to ignore since they don't actually change the course of the RP unless the player chooses to integrate it further.
