Rape culture, what does that mean, and does it exist?

The case of another campus rape done by a sports student who got a lenient sentence has again sparked off the issue as the father tries to defend his son, and the victim tries to defend herself.

Is it ok to ruin a young person's life because of '20 minutes of action' and feeling wretched afterwards? Should there be a difference in rape cases between perpetrators with a promising future, and others?
If not, should the sentence be lighter for others as well, or harder for all? Should frats be forbidden, as it seems that the people there committed rape rather more often than others, and the universities seem unable to deal with the problem?

Should it be limited what you can ask of an alleged victim in court? As for instance what you wear, and all the rest? Should the ruin of this other person's life be taken into account? Should there be more help for rape victims, rather than harder punishments for the perpetrators?

Do you think there might be a difference in attitude towards these cases? Usually, when it is a drunk woman and a sport's person the sympathy is on the side of the perpetrator, but as far as I can follow it, this time is seems to be on the side of the victim?
