I have always felt that to actually see the vomit is unnecessary, the sound effects are quite enough, although it doesn't bother me to the point of feeling ill myself or having to turn away.
What DOES bother me, is what seems to be the endless scenes of gay people kissing mostly on the soaps. We all know there are gay people, and what they chose to do is up to them, but if you watch the soaps, you could be forgiven for thinking that at least 50% of the population is gay, and there seems to be far more scenes of gay people kissing than ordinary couples. I don't know whether they do it for the shock value, or whether the aim is to make it acceptable to the majority to see gays kissing in the street, but I really find it over the top and to a degree unacceptable. Sorry, I've gone a bit off topic, but didn't feel it necessary to start a new post.
